Yet another score motor keeps running thread. Just finished my major refurb and fired it up. It had a few bugs that I worked out and got everything working perfect except the match light wouldn't come on. Adjusted a switch on the game over relay that sends power to those lights and when I fired it up the score motor wouldn't stop running and the bonus unit keeps firing.

All score reels reset nicely, no closed coin switches, game over light is on. I checked all of the switches that send power to the motor and they are all open so not sure where it's getting it's power. Reset bank resets.

I have the schematics but not very good at understanding them.
Looked over all of the relays and all of the switches appear to be opening and closing as they should. I've read multiple threads about running motors and tried many of the suggestions but no luck. Any help will be much appreciated. Posted on Face Book as well

Thank you. I will take a much closer look at the score relays and let you know my findings.

Thanks Currie and Howard. I have already checked all of these switches as well as their solder tabs. All were open.
I will look a them again and do as Currieddog suggested and block them one by one.
Will be a couple hours before I get another chance to look at it.

I'll try that too.

This is what I checked during my lunch break.

Blocked all of the motor power switches and pulled the paper out one at a time. Only the reset bank SB would make the motor run but it should run when the reset bank pulls in. There. must be something that cuts power to that switch. I pulled all the Jones plugs in the back box but motor still runs and bonus unit keeps firing. That should rule out anything in the back box including the 10s,100,1k and 10k relays.

Looked at 500 and 3000 point relays. All switches are open and don't pull in upon powering up.

I blocked motor 1A and the bonus unit stopped firing but the motor kept running. Probably not significant.

That's as far as I got. I think the more things I try the more I can eliminate.

Any other suggestions are much appreciated.

Brake looks to be in good shape with good tension. I've read about motor over run and the problems it can cause.
Thanks for the suggestion.

I'll check that this evening, Reset relay also has P1B and P1C contacts. Should they be checked too?
I can't seem to Find P5A in the schematics. Just wanted to see what else it goes to.

Found it! Bottom of the page.
If the player unit is in the back box and I unplugged all of the Jones plugs to the back box and the motor still runs wouldn't that eliminate any chance the problem could be there?

Feels like I'm losing ground. Before, when I coined up the machine would reset. Now the only way it resets is is when I manually advance the player unit a notch. Then only the score reels reset and the reset bank solenoid does not pull in. When the player unit finishes it's sequence and rests at home position P5A is closed.

While the motor is running I can manually trip or un trip most of the relays without any effect on the motor running or the bonus unit firing.

I feel like it's on the bottom board so it might be time to pull that out and put it on the bench with better lighting and can look at everything from better angles

Will do and report back tomorrow morning "

The bank is well seated and tightened down. SB armature moving as it should. I have been latching and releasing it to make sure the switches are doing what they should.

Going to check out the circuit Howard suggested during lunch break to see if I can get the bank to reset.

Well.........Embarrassed to say, it turns out the 1/2 amp fuse for the reset bank was blown. I found out as soon as I started using the jumper and the bank solenoid didn't fire. Score reels reset, bonus unit stops firing and the motor stops. That silence is a beautiful thing!

It won't start a game though. Ball in the out hole and not kicking out. I'm sure while poking around I changed something. I had to get back to work and couldn't look into it. If I can't figure that one out it will be a topic for another thread.

Want to thank you guys for you patience and help.
