Hi all,
I've been troubleshooting an arcade's Williams Jubilee (Electro-Mechanical). This one has me perplexed, and I'm looking for suggestions / validation of my going forward plan.
Symptoms:
Plug in the machine with the power switch and door panel out of the picture, and you get 120 volts at the transformer terminals and power outlet in the machine.
When you put that plug in, the voltage drops into the millivolt range. I tried this with every other plug out of the board - every time I plug in the switch, the voltage drops to almost nothing.
I have metered the power switch to ground - nothing shows up.
I figure the cord is down to a thread, and when I plug in the board, I pull down the voltage across the bad cord.
My going forward plan is to replace the cord. Does anyone have any thoughts or ideas, or has anyone run into this before?
By the way, it isn't blowing fuses and nothing is smoking, which is why I figure I have a bad power lead, and not something on the board, hard shorted to ground. Something would have clued me in with a blown fuse or smoke at this point.
Suggestions?
