Quoted from brian_owl:
He said that br1 on the board gets its voltage from j6 connector... My question now is does the power go through the solenoid driver board before it gets to the transformer? Could a bad driver board make you not get any current from the transformer.
My apologies, I didn't realize this game used a different power board than the earlier Ballys I'm more familiar with. Schematics (I assume the original and the LE use the same hardware):
The question I would have is did this game ever work in your possession, or did you buy these boards in order to get it going? You say "recently I lost all the power", so that to me means it was working fine, then started giving you issues, but I want to make sure. Which power board did you buy?
It looks like J6 is the connector which sends power from the transformer to the board (printed page 28, pdf page 33), so if you're sure you measured the pins on J6 correctly and you're not getting anything, then I would ensure the wiring going from the transformer to J6 is in good shape, passes continuity test, has solid solder joints on the transformer itself, etc. Some pictures might help. It's very unlikely your transformer is bad, it pretty much takes the intention to kill one, or extreme carelessness to do it, they won't die on their own.
If all the wiring looks solid and you're getting continuity where you should, measure the AC voltage on the transformer itself by putting one lead of your DMM on one lug, the other on the second lug. There should be 2 lugs associated with each voltage (two for 115v, two for 60v, etc. etc.). Putting one lead on ground one lead on a lug won't give you accurate reading. Pdf page 50 for the schematics of the transformer.
The solenoid driver board generates HV for the displays but outside of that all other power in the machine is generated from the power board.
