So I am helping a friend via the internet to get his Bally Dracula working again.
He is having power issues, and I had him order a GPE rectifier board. He had a local "pinball repair" guy install it, and he proceeded to break it, then replace one of the bridge rectifiers on it.
Anyways, then the repair guy installed a Bad Dog in the machine but he was only getting 4.3v on the 12v (11.9v) line. He gave up and left him like this. Some repair guy.
So I had my friend connect his meter on e11 and e12 in AC mode and indeed only 4.3 VAC is coming out of the transformer to the rectifier.
I am thinking that his transformer is bad, although pretty uncommon to happen.
The only other thing I can think is that the connections from the transformer got mixed up and the instead of hooking up to correct wires to e11 and e12 on the rectifier board the wires for e9 and e10 (6.3 VAC) were connected. But 4.3v is really pretty far from 6.3v so I don't think so.
Thoughts? I am going to have him test the voltages on all the other connectors too.
Where would one go about getting a replacement transformer for this pin?
