Maybe create a want to trade ad for a working 11B for one of you DE MPU boards?

Fire was the last sys11a game, 11b would work if I added the missing components, but yes that's a good idea

11B is a bit easier to locate than 11A. Your Diner has a 11C MPU? On 2 occasions , I ran into a Diner and a Pool Sharks, originally shipped with 11C boards, actually have 11B board installed. It works, but overkill in those 2 games.

My diner actually has its original 11c boards minus the power aux board which is aftermarket, I agree , my ad says 11a or b, hopefully someone has one

Post a link to your ad in this thread.

Quick question, is it safe to power the game on while IJ22 (The display data cable) is unplugged? I want to use a logic probe to test the points on the connector if it's safe to do so.

Yes

My Taxi was resetting with no pattern I was able to figure out. The only thing is it did it at times when coils were going off. Today it happened when I hit the ramp to start multiball. It rang the bell one time and reset as it kicked the ball out.

I opened the game and I had actually rebuilt the power supply about a year ago. I have a few games, so I don’t remember all the repairs I do. But, system 11 resets normally mean the power supply need to be rebuilt. Sooooooo, what do you do if you’ve already rebuilt it?

Check you voltages on the power supply test points and then see what you are getting for your +5V on the mpu. Really depends on what was rebuilt. You could still be generating low 5V and with enough resistance through the connectors could be enough to drop you below an acceptable threshold.

I have a buddy about to sell a really nice earthshaker. Is anyone looking for one or know someone who is?

On Diner when I power it up it fires a coil or two, doesn't start up the display, and there is a low level "buzz" type of hum coming from the speakers. It has failed to boot in the past (and I have replaced C30) but didn't have the buzz like this. The LEDs on the MPU from left to right are solid/off/off.

Seems like 5 volts is too low coming from the power supply. Measure 5v and 12v on the test points of the power supply. Seems like it is time to recap the power supply.

I have several System 11s, so cant remember which power supplies I have and have not rebuilt. If I have already done that, is there a next step to look at? 5/12v at power supply and at MPU?

Measure at the power supply as I mentioned. If it is bad from the source, no need to measure at the MPU.

Gotcha. I’ll be back at this location on Saturday. I have a cap kit but have to confirm its for the correct board set.

Pretty positive Taxi and Whirlwind have the same power supply as Diner.

If you have 12 volts measuring less than 11.90v, then you probably have a bad bridge rectifier as well as needing replacement.

Here are the capacitors..

This, been seeing this issue pop up alot lately
Line voltages go rough or slightly low , and the bridge rectifier is usually involved

I've started my F14 shop job. Have the top mostly removed. Started to test mylar removal using the freeze spray method and I'm getting nowhere. I've had luck in the past, but the mylar isn't budging. Do I need to keep laying the spray on heavily? It's been years since I've had to do a mylar removal.

Thanks,
RC

start a edge, spray heavily keep peeling back as you constantly spray.

friend might have dibs on one in the next week or 2, it will be for sale here In st. louis.

I'll revisit tomorrow night. Maybe I didn't spray heavily enough to get it started.

Congrats!

I am hoping to re-join the club soon.

Play better and beat the existing one!

Did you try a factory reset?

Interesting, i actually never tried. Mine reset when i swapped out the batteries for the nvram. You could pull the batteries if you don't have nvram installed.

Got back to this. I tested the upper playfield section. Freeze spray worked. Just blasted the area more than I was doing before. Getting the glue off is going to be extra challenging with all the raised inserts I have to deal with. Here are a couple pics of the worst areas. Basically every small arrow is lifted. The medium and large ones are fine and any round inserts also fine.

My Diner diverter is spasming at random moments of gameplay. It happens for a second or so and then goes away. Anyone ever seen this to guess what’s up?

Solved: the spring that connects to the coil plunger had broken and was making the diverter look like it was fluttering. Fixed now.

More fun with Diner. When I turn it on it gives a credit dot. Checking that it says something like “can’t raise lift ramp”. There was also a ball sitting in the right side Today’s Special scoop. When I retrieved the ball the outhole kicker shot it into the trough, so that coil works. When I turned it on and pressed start when I first got to the game it did a ball search with several coils and said pinball missing. So at least some coils are working.

Once all 3 balls were in the trough, I pressed start. Instead of kicking a ball out and starting a game the display did a slow motion powering off thing. GI was still on, but the game seemed to freeze. I just did it again and the display didn’t power down, but the inserts looked like it started a game, but the game made a bong sound and then went into attract mode. I’ve never seen a System 11 do this. I did a cap kit on the power supply a few weeks ago, so the power supply should at least be happy.

Not sure if this matters, but the relay on the aux power board (bottom right) clicks 5 times when it boots. Not sure if this is normal or not, but it happens.

It could be the operators notification....

Knocker coil not working?

I can see this as being the case. I had this turned on for my F14 and it drove the location crazy, but nobody told me for a while so I could actually fix it. I don’t want to pull Diner to dig into it, but it’s looking like I might have to.

I went over to the location today to fiddle with Diner. After researching a little about resets I was going to look to see if a switch was stuck in the same "corner" pattern of the switch matrix as the slam tilt, but to just check the slam tilt first. No switches were stuck. I don't know if it alerted me or I stumbled on it, but the second (upper) switch in the "Today's Special" scoop wasn't registering. I was looking in that area because a player said that it wasn't kicking out from there when it was working.

The lower switch was working just fine, but the upper one (why is there even an upper one?) was not. I figured it was bad since it wasn't clicking. I removed the screws, and it was clicking again. Ok, let's bend the lever so it releases the click. Done. Press start. Game doesn't reset, so that's a good start. Was that the issue? No clue. Playing the game that kickout still wasn't firing the ball. Same thing with the lift ramp to lock the ball. Under the playfield I see that they have the same wire providing power. The multimeter that I keep in my tool box in the car is not working, so I was trying to inspect things without it, but with an ACE one lot over I could get one if I needed. I found what fuse was for that coil group and sure enough the fuse was blown. Not sure what all happened, but I'm guessing that the switch getting stuck caused the coil to lock on and then blew the fuse. After a few test games everything was working so fingers crossed.

Guys thoughts on bk2000?

I’ve owed most system 11s. This one I haven’t.

I like progressive jackpots and not sure this one has one.

Thoughts on it?

Love my BK2K. Fast paced and a challenge to keep the 3 ball multiball going.

Lots of love for Bk2k out there.

Best looking Sys11!

Best sounding Sys11!

Unfortunately boring to play. Hey, don’t shoot the messenger!

Up the top. Rinse. Repeat. If you are a decent player, it’s a grind. Hilton argued there’s lots to do down the bottom. But why would you do that and risk draining (you will) when you can safely and easily shoot it up top all day long. And I mean ... all ... day ... long ...

However, if you just want to look at it, or listen it it, you can’t go wrong.

Thanks for the write ups.

I have played it a few times and thought meh.

Just thought owning may show me
Something different.

Have to agree with Dave here. Gorgeous, but boring.

One day I’m going to take the wireform off the front of the upper playfield ... so when the ball comes down through the WAR lanes, it doesn’t always just land on the left flipper.

That should spice things up a bit!
