Quoted from Buzz:

It looks correct and yes you will have to solder about 12 or 15 wires to the board. Use small gauge solder to help. I also use some heat tape to hold in place and clip and re strip the wire and recrimp any burnt connectors.

No, the -54 are all connectors. No soldering needed to replace.

What the op is looking at is correct. The bridge rectifiers are just mounted on the topside, with a heat sink on it.

Quoted from Buzz:

Wow sorry I own some Ballys and none have rectifiers in the cab and just thought they would all be the same just different location. Well hell that's a lot easier. Sorry for bad information but still believe the rectifier and burnt pins are the place to start. I love this place and the information that gets shared.

Yeah, the rectifier in the cabinet is a much better design, and way easier to work on.

Quoted from Matthew2015:

unplugged J1 though J4 connectors and it still blew the f1 fuse.
so that narrows it down to the transformer or rectifier board , right?
i bought a power rectifier board and some more fuses so i will wait for that before doing anything else.

It sounds like replacing the rectifier board is the next step. The old one could probably be rebuilt, but most likely isn’t worth your time.

Quoted from Matthew2015:

just got the new rectifier board.
taking out the old board but has wires attached to some bridge rectifiers on the side
but the new one won't need those , right?
i think someone already tried to rebuild the old board already.
also wondering about what the large plastic dome thing does .[quoted image][quoted image]

Yes, that is someone replacing the bridges and wiring direct to the board (and with a big ass heat sink). You can take all that stuff off. You won’t need it with the new rectifier board you purchased.

The plastic dome is a protective cover for the power switch. It is original from the factory.

Can you post the voltage you're getting from the rectifier board, and the solenoid board?

Also, is the green led on the mpu blinking at start up, or just locking on? If blinking, how many times?
