Had some friends over last night, Funhouse had been working properly till then. Three problems came up at the same time, so I'm not sure if they are all related. Here are the problems:
1. Rudy Jaw: Has stopped working properly, it will close on game start up but will not open during game play or in test mode. I've checked the gears and no teeth are missing and I can move it freely by hand, so it's not stuck. I've also tested with a 9 volt and it works properly in both directions. Checked the connections to the small diver board in the back left corner and they seem to be ok.
2. Steps gate: Will not open in test or gameplay. Checked the relay, no connections hanging and it's not burned out.
3. Trap door: It will open but not close back down. The coil that opens and closes doesn't seem to be the problem, but the relay that actuates and allows the door to come down is not working. This is neither burned out or have connections hanging.
I've read about issues with the small jaw driver board causing problems with the motor movement, but since these problems all came up at the same time I thought they might be connected to an issue on the main driver board rather then just an issue with the jaw driver board. I have some repair experience, but not much with board work, so I'm hoping someone can point me in the right direction.
