As the title states my Amigo starts on ball 2 instead of ball 1 so my 5 ball game is only 4 balls. I've worked on my 4 solid state games a lot but never on an EM. Any help would be appreciated.

Find and repair/correct any mechanical issues with the Ball Count Unit.

Lol that is just answering by rephrasing my question. Anybody else have some info on this? Maybe a pic of what I will be looking at. On my solid state I just went through a switch test. Located the trough switches not working and replaced. You will have to excuse my lack of knowledge on EM's but I will learn just like I did on SS games.

Find the Ball Count Unit. It should be marked. It is a stepper unit that only increments 5 steps. Usually only three fingers on the wiper blade stack.

One solenoid resets it to Ball 1, the other solenoid increments the wipers and gear by 1 ball each step. Start game and if the unit only resets to "Ball 2"; study the unit and eliminate the bind preventing it from zeroing. It is probably gummed up. Clean the rivets with alcohol (game unplugged, wait for alcohol to boil/dry completely before turning machine on). Conversely, you can sand the contact rivets with fine sandpaper to remove the gumming stuff.

If this fails, add tension to the clock spring.

Thanks! I'll give it a look when I get home from work and report back.

I'm bringing up this old topic. I never got around to fixing this so amigo just sat for a long while. I have all my other projects fixed so time to knock this one out...... Hopefully.

The entire ball count mechanism seems to work. I manually advanced and reset the unit by hand about 20 times without a single issue. The game always reset fine. Obviously the ball was out for this. When I put the playfield down, and tried to play, it immediately started the game on game two...... WTF. I took the ball out and put the playfield up and once again, it worked perfectly. Once I start a game with the ball in the trough, it goes to ball 2 every time. It has to have something to do with the trough switch. I'm kind of lost though cause all the other balls cycle properly. Can anyone help me out?

To expand on things, there is another issue where if you get an extra ball, it never goes away no matter how many times you drain the ball. I can manually change this. Looking at the schematic, the outhole and extra ball are related so maybe this is one issue causing both problems.

Did some other testing this morning. With a ball in the outhole, I start a game. It properly moves to ball one but then switches to ball 2 before moved to shooter lane. Something in the sequence doesn't have enough time to do what it needs to do to shoot the ball to shooter lane before it registers a ball drain. It's only when you first start a game and no other ball is effected. How does a game startup process work? Any ideas?

I can start a two player game and it properly starts on ball 1.

Bump. Anyone have any suggestions?

Verify that the ball count unit operates quickly to reset. Then trace the circuit and determine why the ball count step up coil energizes when it isn't supposed to.

Now I can't hit the credit button to start a game lol. I'm lost.

About to call in for reinforcements.

Advance the credit wheel up to something beyond "0".

#14 3 years ago

I'm back up with the start button working. Now I don't advance past 1st ball on drain. These things are very touchy. I spent a bunch of hours reading about em's and reviewing the schematics. I'm starting to get an understanding of things. Hopefully I can get things moving in the right direction.

It sounds like the Ball Count Unit has a mechanical bind. Verify proper operation by manually operating the step up solenoid and then the reset solenoid plungers.
If there isn't smooth operation, remove the wiper finger assembly and clean the rivets, replace, and don't tighten down the locking screw & washer as tight as it was.

I did that yesterday. It works perfectly when done manually. I'm not seeing the coil fire now when the outhole switch is activated. I'll just go through the schematic and see what I screwed up. Working on my first EM is definitely different. I appreciate the input you have provided so far. At first I was lost. I'm starting to gain some traction.

I definitely think. I have some iffy connections. I ended up knocking. Out the playfield gi. The big connector in the back of the cab was the culprit for this. I'm back to having the balls advance and my gi is back but I still have the issues of the game starting a single player game on ball 2 and the extra ball never turns off. Lots of hours to end up back in the same place. Could the problem be in the score motor? Am I missing something in one of the processes? What normally prevents the game from registering a drain on startup since the ball is sitting in the outhole? Any help is appreciated.

You did reseat all the Jones Plugs, correct?

#19 3 years ago

Yep. That's what caused me to lose playfield gi. Maybe I didn't reseat that one properly the first time.

Did you ever solve your problem with your Amigo? I have a Teacher’s Pet that, when the ball is in the trough, starts up on ball one, but as soon as it’s pushed out into the chute, the game switches to ball 2. Betting it’s going to be the exact issue you had.

Wow, this is identical what is happening out of the blue to my Amigo. Ugghh!
