Picked up a Bally Truck Stop the other day. Currently at power on, all of the coils lock on and the 2 fuses under the play field blow. The fuse for the coils on the power supply board is NOT blown.
Any ideas what would cause this?
At power on, the coils all lock on, the under play field fuses both blow, and the game continues into attract mode as it should. You can go through the diagnostics, change the settings, and start a new game up just fine. All the switches work and score as they should on the play field, but obviously there are no coils working.
This was not happening when I picked it up and set it up back at the house. At pick up it had a couple small issues:
- stand up target would stick to the pad behind it causing scoring whenever you hit the flippers (adjusted)
- same segment out on all digits on on of the displays caused by a bad transistor on the display board (replaced transistor)
- some lights out here and there, went into test mode and replaced all burnt out lights with the exception of one of the 912 flashers. when you put in a new flasher, it and the other flasher associated with the same q transistor both stay lit all the time. When you remove the one that was burnt out, the other flasher works normally as it should.
Other wise it was playing as it should. As it sits now, the one flasher light is still an issue, but otherwise all lights work as they should all switches score as they should and none are stuck, however, all the coils lock on at power up and blow the under play field fuses.
Other than looking for something I might have bumped that shouldn't be touching while I was replacing lights, any other ideas?
Thanks!
