Hi Pinside,

I'm working on cleaning up a super mario bros that had some pretty serious humidity damage for a friend. I've got everything sorted out but I can't seem to get the castle to spin. The motor spins freely and I can see the rod the plastic spins on turning if I spin the motor over by hand. I've checked and I see the motor relay engaging when the game calls for to motor to start. Also the relay works fine in the solenoid test. I find I am not getting 50VAC at the motor lugs but I'm somewhat stumped on what to try next. It feels like a fuse but I checked all the ones I could find.

So two questions
1. What should I try next
2 During the solenoid test if I turn the motor relay on should the castle start turning? To test I started a game and got into super mode then lifted the pf and checked for voltage at the lugs of the motor and got nothing.

Thanks a ton!

Interesting, dumb question, for the leads the relay closes should I get continuity on one of the legs if the relay is closing correctly (If I understand correctly all it is doing is manually closing that switch to supply voltage or a ground (Return). (Game Off) I would put one lead on the leg of the switch that gets pushed into the stationary leg and the other lead on one of the coil legs for the motor should I get continuity? If so does that mean the relay is working correctly?

Thanks!

So the relay was an issue for sure. I am now getting 50vac at the connector but the motor doesn't turn and I still get 0 v across the lugs on the coil for the motor. This makes me think the coil is internally open or for some reason not connecting to the motor housing. I get continity across the lugs so I don't think the coil itself is the issue but even if it was I don't think this is the type of thing you can just crack open and work on lol. Time for a replacement I guess.

No worries. I dug into this more and after I fixed the relay (The contacts were super corroded) I got the 50VAC at the connector for the motor. The motor is just internally open (Dead), and It's riveted together so I don't think it was meant to be serviced. Replacing the motor will resolve the issue.
