Hi,

I am trying to get a Dancing Dolls up and running. All stepper units are operating freely. I have the schematics.

Currently if I hit the start button the score motor briefly turns (Turns 1/4 revolution) and the S relay, Hold Relay, U Relay, and Dancer Reset Relay are energized. Point Unit and 100,000 unit will reset. A credit is subtracted and play meter goes up. Lights come on. All of this is over in about one second and the game is dark again. I am trying to figure out the start up sequence and have been referencing http://www.pinrepair.com/em/index3.htm#start.

I am also not sure if the 100,000 unit and point units wipers are adjusted correctly and am confused about the -1 position and zero position.

It seems like that is where the action stops as I am not getting the ball release solenoid and am not getting any 10,000 unit motion.

Any ideas for me?

When the reset process stops, the lights on the playfield and backglass turn off? If the machine turns off during the reset process, most likely there is a faulty coil in a circuit that is related to the start up process. Visually inspect the machine for any burned coils and solenoids...

The reset position of the 100,000 unit is called the -1 position. At the start of a new game the 100,000 unit reset coil fires and its wiper disk unwinds to its -1 or reset position. The 10,000 unit should then advance (not reset) until it reaches its zero position. Once the 10,000 unit is back at zero the 100,000 unit takes a single step to its zero position and the game should be good to go.

During the reset sequence, a normally open (NO) switch on the U relay should close allowing pulses from a NO score motor 1A switch to get to the "Add 10,000 unit" coil. Since the U relay is firing, I'd check the NO switch on the U relay (slate-red to black-red wires) and make sure it's working properly.

Everything seems OK on a visual inspection. I did find some wires had come off of some switches on the score motor. I resoldered them (so much fun!) and nothing has changed.

When I got the game there was a switch that was bent on the Start relay that just kept the score motor turning. I jumpered the switch so the score motor would keep turning and the 10,000 unit did advance to 0, and then the 100,000 unit steps up. This makes me think that the 100,000 unit is in the correct -1 position.

U relay seems fine and switches open and close as they should. No wires of that color, but because of my jumper experiment I feel that this has been eliminated from the troubleshooting for now. I will keep poking around on this thing today.

Thanks for the help so far!

Ok, so the issue seems to be that the score motor isn't being run long enough to let the game finish resetting. Series switches on the U/Reset and S/Start relays both need to close to run the score motor, as does a switch on the Q/Dance At Reset relay. I wonder if the Q relay gets the motor started briefly as you observed, but that the series U and S relay switches aren't closing to keep the motor running.

OK, I found a wire on the hold relay switch that had come off. I swear I checked that a few times. Like most things it suddenly makes sense. I think it is starting OK for now. Next step is to figure out why no "points" seem to be scoring (Points not being the 10,000 and 100,000 scores, but the single digit points).

I had been manually holding the relay and was wondering why it wasn't working, but if the switch was missing its wire, that explains that!
