Electromechanical pinball machine score reels problem

[BR549 Auto Sales]

I am working on an older dog of a game (Sonic Super Straight) and as points roll up, it won't advance on the ten thousands reel, the thousands reel just rolls back to "0" and it wont advance on the ten thousand reel as it should. The coil for the 10,000 relay is working (it pulls in) but no advance. If I roll it up manually, it will re-set when I start a new game. Any of you pinheads have any ideas on this? I have worked on Bally, Gottlieb and Williams games em machines in the past and I would just clean all of the stepper unit contacts, bottom cabinet contacts, etc. and usually had good results, but this is a new problem to me.

Thanks,

David

I'm assuming these reels use some sort of ratchet mechanism to advance the counters. Maybe a stuck lever or broken spring?

Would they still rotate back to zero when starting a new game though after I have manually advanced them ahead?

For what it's worth, it is the same for player 2, 3 and 4 as well, not just player 1.

I'm just guessing that a different lever resets them. sort of like those handheld mechanical counters where one button advances and another resets. Can you observe how the other ones operate while they are advancing?

<edit> If they are all doing it, then I'm at a loss. Can you post a picture of the assembly?

Maybe some help about halfway down the page. Talks about about a seperate reset solenoid.

wel, they pull in according to how many times the 1000s points rollup, I was thinking that it may be an issue with a contact in the main drum unit in the bottom of the cabinet, it will ore than likely just take some time to track it down..........slow process with these mechanical pinball machines. After they get to working though, they are pretty dependable as long as you play them a few times a week.

See the link above. They show two different types. I was assuming it has the solenoid ratchet type.

someone might have resolder a wire to wrong place , we had a guy that we didn,t like that bought em games  off a big resaler of used games his guy would move a wire on a stepup unit  before the guy came to pickup his pins , he would give up on them quick and bet us we couldn,t fix them , we beat him out of alot of cash over the years and he did turn into a nice guy after that, when we sold em pins to homes we had all kinds of shit happen when the home owner  got their hand in the pin, so you got your work cut out for you , also make sure the head and body have same number on them one could be wired wrong , we have also seen the wiper taken off a unit and put on in wrong spot  most will go on in 2 places, good luck
