I've cleaned the steppers in the game. Player unit has had switches and rivets cleaned, light layer of teflon gel lube applied. Same for all other steppers. Backbox relays have had switches cleaned and the seem to operate properly by hand.

When pressing start at a game over state, the game goes through it's reset process. I'd like to note that a credit is not subtracted from the credit unit, if that means anything to the EM experts.

The Z1 relay engages and tries to reset P1 and P2 reels. For this test, I started with a 1 on each reel on purpose. I get the result of the first pic and the score motor continuously resets.

Z1 is locked on. If I manually open that relay, then Z2 engages and does the same thing. I end up with the second pic with the score motor continuously running.

Seems the thousands and ten thousands won't reset at all during this process.

If I set all reels to zero, the game will go into game mode and play a game and score, so I know those reels that won't reset during game start do function properly.

This is my first Gottlieb EM, so any advice is surely appreciated.

Thanks,
RC

Thanks for the advice. Double checked the 8 reels that won't reset.

All of them have the switches adjusted correctly. Cleaned them with the flexstone just to be sure.

Verified they operate just like the reels that do reset.

It seems weird that it is the same 2 positions (10K and 1K) on all players. Could it be a larger issue in the relays or player unit?

Indeed. I just received the schematics. A friend mailed them to me. I need to get better at reading them, but I have come a long way, from being totally dumbfounded lol. I'll check that switch right away.

That was the problem. Thanks Howard. I thought I had cleaned all the score motor switches, but that one was hidden and tilted differently than the others. Filed that switch, as it was making good contact, already. That got the other reels resetting. Woohoo.

Now, the pops seem to lock on the 100pt relay. They also don't pop. I'll dig into that on the schematics. The 500pt lanes don't do it. I really do want to be able to figure this stuff out for myself, but you guys are invaluable.

Thanks,
RC

The 100 pt locked on issue was resolved by cleaning these 3 relays that handle the pops.

The left and right red bumpers fire simultaneously no matter which skirt switch is activated. Based on what I see, that seems correct.

Final issue is the right side monkey drops don't reset. That coil doesn't seem to activate. Into the schematics, I go

Final issue was a fuse. Lol. Tested with a circuit breaker before wasting a fuse. Seems good. Woohoo. Now to finish cleaning her highness up.
