I have a 1980 something standup video poker machine. The question I have is what does the nicad battery do that is on the circuitboard? I have replaced all the caps and still popping the one diode and drawing 15 amps on a 1.5 amp fuse.

I think you need to be a bit more specific on the brand, IGT, Bally etc...

The purpose of the battery (lithuium not nicad) on the IGT is to maintain the CMOS settings when the machine is off.

I am not sure of the manufacturer of the machine. The battery is dead and I can make out nickle on part of it and ge. I am inclosing a picture of the board.

I don't recognise the platform - hopefully someone can jump in here an help us identify the board.

I have an idea of what it might be -- I sent an e-mail to Stolistic to have him visit this thread and confirm or deny my suspicion, as he knows some of the older poker platforms.

if you're blowing a fuse immediately at power up, i would
suspect one of the bridge rectifiers in the power section is
shorted.

So far what I have done is changed two of the gold caps, and all of the siler ones around the edges. I also changed the bridge rectifier. It solved one fuse blowing now a 1 amp fuse blows as it is drawing over 15 amps. The larger blue cap checks ok, but of course with it out of the circuit it doesn't blow fuses. There was also a blown diode right next to the bridge rectifier that blows If i leave the machine plugged in for more then 3 secs. I hope this helps someone to give me ideas on what else to look for.

Ok for some reason I can read ac and dc voltages on the positive side of the gold caps. Does tht sound right?

The battery holds the books information (money taken in and paid out) and will keep your credits when you power off the machine.

While you have the board out of circuit, Use an ohmmeter to find the short(s) to ground. Divide and conquer!
Start with whatever is in line with that diode that keeps blowing.
Obviously you will have to remove components from the circuit to narrow down the short(s).

Good luck.
