Thanks for the replies. I'm still having trouble accessing the replay unit itself, it's one of the half moon replay units on this machine, I've attached a couple of pictures. I'm having trouble even accessing it but there are no visible screws for me to take off to have a look at it. If someone could help that would great.

Also, one of the flippers make a humming/buzzing noise when actuated, would this be an issue with the coil?

Thanks.

Not a big deal about the replay wheel. I'll just leave that. I'm just happy that the coin mech works so I can put in one credit at a time.

I was just fiddling with some stuff and the indefinite game issue isn't happening anymore, however there are a few more issues I'm starting to notice.

1) Both flippers seem to be kind of weak, is this due to the coils getting old or is there something else I should look at for this issue.

2) The ball play lights always light up for ball 4 and 5, but 1 and 2 rarely light up and 3 sometimes does. Sometimes when 1,2, and 3 light up it's part way
through the play for that ball, I tried replacing the #2 bulb since it has never lit up but still nothing? What would the most likely issue for this be, the sockets
perhaps?

3) Sometimes the ball in play skips #2 and goes to ball #3 so then I only have 4 balls instead of 5. Any ideas for this one?

4) How do the red balls in the animated back glass work in terms of points awarded and when are they suppose to be reset and pushed back down out of view? I find they sometimes get pushed down mid play when there are only a few red balls in view and I don't think its suppose to.

willbeEM I'll check out that dremel brush.

Thanks again for all the help, you guys are really helpful!

HowardR If you could post the schematic fragment that would be great. I think they seem okay, shifted a little to the right but not much, here's a picture of it, let me know what you think:

Okay, I'll check this out tomorrow. I have one quick question though. Inside the dashed lines for the player unit what does the 0-1, 4-5, 8-9, etc connections represent? Is it just to do with the couple of connections that get closed as seen in my previous image (post #60)? Thanks.

I finally got around to testing some of this stuff out, here is where I am at:

1) I was looking at the player cam and I think it is in the incorrect position to light up the ball in play light. For example, for ball 1, according to the
schematics, the #1 light turns on when the player cam closes the connection with the blue-red wire. However, when I was playing with ball #1, the player cam
was closing the switch with the brown-red wire (#3 ball). Also, for this example none of the ball in play lights were on. Has anyone delt with this before?

2) For the flippers, I adjusted the EOS switch a bit and I did a little bit of cleaning with a business card. I think it improved them a bit but it still doesn't seem to be quite there yet. I was planning to do a more extensive cleaning with either a nail file (emery board) or 400/600 grid sand paper. What would be best to use?

Also, one of the flippers gets a little stuck sometimes resetting, I think the sleeves/plungers in the coil may be a bit dirty. What would be the best way to clean these?

Thanks!

willbeEM Thanks, I'll have to keep any eye out for a good priced dremel, currently don't have one.

I've looked at the player unit cam and it seems to be in the correct positions even though the ball in play doesn't light up most of the time. It lights up sometimes for 1, never for 2, sometimes for 3, usually for 4/5. Also, ball 2 is sometimes skipped or it changes to ball 3 mid play, I have to play some more games to check this out. I haven't looked at the stacks themselves yet, something for me to do over the weekend.

While I was looking at the player cam I noticed one of the player 2 score reels(hundredths) doesn't reset properly, just moves one position, but the game still plays. The score reel itself looks pretty good, it has a very smooth, clean actuation so I don't think its a mechanical problem with the reel. I've noticed a good number of the score reels switches need some adjustment, a number of them either only stay open or closed when being actuated so I have to see what's going on with these. Another thing for me to do this weekend. I don't know if this could related to the ball in play light issue.

Also, the flippers have improved quite a bit, mostly due to adjusting the EOS switches.

Thanks!

Hey everyone,

I got the ball in play light issue figured out I think. Every once in a while the first ball seems to be skipped but for the most part it is working.
I'll have to play it more to figure this issue out.

I also fixed the score reels and they are resetting properly.

Right now I'm trying to figure out how scoring is working. I'm a bit confused on how many points should be scored.

For example, should I get points every time a target/rubber kickers/rail (don't know if rail is the correct word but I mean the depressable metal that balls roll over) is hit? Currently I don't always get points so I didn't know if I should.

How do the bonus lights work? I find some are on and they tend to just stay on, they don't seem to change if I hit the target or the metal switches that collapse with he lights on.

Also, this one is likely directed to you willbeEM since you own a top score, how should the animated back drop work? Currently mine is clearly not working properly so its a bit hard to tell. I was wondering if you could tell me which target shoots a ball up (is it only the one with the red light and is it only when its lit)? Are they also only suppose to reset after each ball is lost?

Thanks!

Thanks for the replies. D-Gottlieb - Ya I'm sure this machine needs a lot of things tuned up, don't really know its background, I have a feeling it hasn't
been in operation for a while. This is my hobby project at the moment so I'm enjoying fixing things up myself. I have one thing I want to clarify about what you said earlier. Did you mean that when the pop bumper lights are on, the rollover should score points? Since what happens with mine is that the lights are on typically and then the lights go out when the ball actuates the rollover and then the lights come back on shortly afterwards and typically points are scored.

What happens with my machine is that every time a rollover/target are hit, either 0, 100, or 200 points are added typically and every few actuations 500
points are added (is that some sort of bonus since I see a 500 point relay in the schematics). Also, when it scores those 0, 100, or 200 points, the matching
number of chimes occur as well. I was reading on another thread that it could be dirty motor switches, is this possible, or is there another likely cause?

The kicking rubbers get 10 points and this seems to always be 10 points and the bumpers always get the corresponding 100 points as well.

I'll check out the red ball issue later, but currently what happens is that the red balls are shot up when they are suppose to be but when too many balls are up
there eventually one falls out (what ever is holding them up there must not be properly adjusted).

Thanks for all the help!

Ah okay, that explains why I was getting such a small number of points when I played, I thought it was just suppose to be 100 points for each rollover/target. I do get a sort of repeating pattern for the amount of points received for successive rollovers/targets. First is usually 0 points, the second is 100 or 200 typically, and then the third time its usually about 500 points. I'm a bit confused as to why this happens though. Isn't it the same switch closing each time? If so I thought it would get around the same number of points for each target/rollover. Obviously I'm wrong since the amount of points varies in a pattern of 3. If you could explain this that would be great.

So, I was also wondering which switches need to be cleaned on the motor? In the manual I see "Motor 1A -third switch" labelled for scoring so I was guessing it is this one, or are there others. According to the schematics I see another path with Motor 1c that connects with the targets/rollover switches but the manual does not say anything about scoring for that one.

Earlier, when I was talking to willbeEM he said it's best to use a dremel with 443 brush for cleaning contacts, I still haven't picked them up but I do have 450 and 600 grit sand paper, would it be best for me to get the dremel/brush first before I try to clean the contacts or is it okay to use the sandpaper?

Thanks!

Hi everyone,

I ended cleaning that 1A third switch and nothing else, however I have new issues after I did that. It did fix the scoring issue though, targets/roll overs always get 500 points now.

The new issues are that the 1st ball is always skipped, well what happens is when I turn on the machine and add coin everything resets and before I put the ball in the outhole it says ball in play is 1, then once the ball is put in the outhole and is ejected, then I plunge it to play and after a couple things that rack up points the ball in play 2 lights up). I was having this issue rarely originally but now it happens all the time.

Also, once you sink a ball it stays in the outhole for a really long time (>1 minute) before it is ejected for play. Similarly, this happens with the mystery bonus hole as well, could these be other issues that were masked by the 1A switch not working properly? Or could cleaning the 1A third switch adjusted the switch to cause these issues?

Thanks

Thanks for the replies:

HowardR

So the player unit goes to the #1 ball in play position after the score reels are reset, the ball in play #1 light is also on. The player cam stays there after the ball is put in the outhole while the ball in play #1 light goes out when the ball is ejected from the outhole. Then once the first bunch of points are accumulated the player cam moves to the #2 ball in play position, this is the same time the ball in play #2 light turns on.

yes I hear nothing happening inside the machine while this is going on.

willbeEM
yes all the holes are slow. What do you mean by the score bonus hole, I know of the mystery, 1000, and outhole. One thing I've noticed is that it's also not always slow though. Sometimes it can be faster. Is this likely just a dirty switch? I've been reading some of the forums/wikis and I know I've seen them talk about delay switches but I don't see anything on the schematics stating that so I'm guessing there should not be a delay, is this correct?

D-Gottlieb
Yes I do have the manual and schematics. I've looked at clays guide and that wiki that you have sent me as well, I think I just sometimes get overwhelmed with how much there is on the schematics. I know Clay recommends not to clean switches if your a newbie, such as myself, and so that's why I've been going about this one issue at a time method. I also gave a look through all the switches to see if they were properly opening and closing.

Hey Thanks for the replies.

HowardR To answer your question, yes the player 1 lights are on the entire time.

jrpinball Okay I did notice that mentioned in the wikis/clays site. I'll make sure to check the screws first before I start adjusting anything on any relays.

D-Gottlieb Alright, I guess it probably would help if I checked out all the screws in the switches and to do some cleaning of the switches, I'll just make sure to keep it light.

willbeEM D-Gottlieb : I haven't looked at the KS relay yet since it didn't seem to be causing any of my current issues. Is it somehow connected to the issues I'm currently having? Or just something that commonly has issues?

Over the next couple days I'll have a look at some of my potentially bad switches which I've been having issues with in the past and make sure they are cleaned up and everything.

Thanks for the help.

Slow ball issue is fixed, it was the switch on the I relay, needed some cleaning, still have the ball in play issue but at least I got rid of the slow eject ball.

I was also reading on the pinwiki about a zero position for the player unit cam that section of text also said those pictures only pertained to single player
machines. I was wondering if any of you knew if this was true for this one as well (I'm pretty sure it would just wanted to double check)? If its the same position as the one I have uploaded here from the wiki please let me know. Thanks.

more good news, I found the issue for the ball in play stuff, it looks like it had to do with a P relay switch not closing completely, tightened the stacks, a little cleaning, and a small adjustment got that fixed.

Next thing I'm working on is the bonus relay, it doesn't reset the backbox animation properly, usually missing a few balls. I have found out the reason though.
It seems to be due to the piece of metal that connects the ramp in the backbox to the main metal sheet in the backbox being snapped. This makes the ramp
slide forward (towards the player) and so the balls don't sit on the ramp properly. It looks like it was welded back on but then it snapped again. Are there any
super strong adhesives that anyones perhaps used to keep metal together? I've never welded anything and don't know anyone who has which is why I'm
leaning towards some sort of adhesive. Or if anyone has any ideas how to anchor in place using another method that would be great.

Thanks!

D-Gottlieb and willbeEM (since you guys own top scores and have half moon replay units): I'm also looking at the half-moon replay unit again, how do you guys add credits to it? I think mine is physically not working, when I try to add credits at the coin door, I can see it budge but do nothing, I'm just wondering if this was a common physical issue with these that could be fixable.

Hi Everyone,

I've gotten a lot fixed up over the last couple days. I've got the half moon replay unit working, for some reason the screw in the unit was in the wrong position, don't know why it would have been moved but once I fixed that everything seemed to work.

Also, I jimmied up a solution for the bonus ball ramp. I bought a 3/4 inch wide flat metal bar, cut it and bent it so it could support the ramp and then secured it to the wood above the bonus ball unit in the back box.

So now I have one more issue I think, as you guys mentioned earlier it has to do with the KS relay. Something is not working right on it but I don't know what. Currently, when the spinner spins the light that is lit up in front of the spinner changes. However, I think I read in another topic that it should reset to the 5th light each ball/game. Is this correct? Also, the A relay never actuates so the bonus lights in the two lanes never switch and from the schematics this is controlled by the KS relay but I don't understand what it means when it shows KS(|) in the schematics for that switch, could someone explain this to me? Also, could someone just state in general what is suppose to happen with the spinner/KS relay upon start up of the game and as you play the game, that would really help.

Thanks!

I fixed the issue where the KS relay would not reset to the 5th light. It had to do with a switch on the KS relay not closing (I think this is the '5th pos. bonus unit'). So I adjusted that and now it's all good.

Also, I think I found the issue with the alternating relay, it seems like the switch that controls that on the KS relay also isn't closing. Just wanted to ask you guys one thing about this, are the rollover bonus lights in the 2 lanes on the right side of the play field suppose to alternate every time the spinner is spun? Just wanted to make sure this was true.

Edit: I fixed the alternating relay issue it was the KS relay switch not closing.

Thanks!

One more bigger issue I caused myself early on was accidentally leaving the ball in the playfield and lifting it up causing it to fall and break a piece of the plastic... It's the ball guide in the top right of the playfield just before the two lanes (picture below). I was wondering what the best way to try to fix this would be. Of course getting a new piece of plastic would be great but I was looking at the plastic sets online and they are pretty pricey and I only need the one piece as well so I don't really want to buy the whole set. I was reading epoxy would be a good solution, I was wondering if anyone had to do that and how well it worked for them? If anyone has any other recommendations that would great too. Thanks!
