Resurrecting an old thread.

This is from Medusa. I have the neutral (ribbed) on the right, and the hot (smooth) on the left. This is the opposite of your Bally SS picture.

I have a new cord and intend to fully replace the old one (ground plug cut off), but I also don’t want to die. Am I looking at this correctly?

Perfect, that makes sense, thanks Vid.

Thanks guys, up and running.

Not so fast.

The game ran for a minute and then died. Apologies for the noob questions, but what’s the best method to pinpoint the issue at the filter? I ordered new 130V MOVs just in case, but with my multimeter, how can I test voltage?

Best source for a replacement filter if that’s the issue? I didn’t see the same type at Marco, but I’m working with a 40-year old filter.

Yes sir. 122V

However, my wall plug GFCI keeps tripping. Normal voltage for a minute, then nothing as the breaker trips. Nothing from the game at all. I tried a different plug with no luck.

Bad MOV? There’s some hacked shit running from the filter to the alternate power plug. Just seems weird it was running for one minute and then totally died.

In fairness, this was in conjunction with a playfield swap, so it could be a number of other things.

Thanks Vid. If my line filter is shorted or bad, would a generic 115V replacement line filter suffice?

I forgot to post resolution to this. My problem was with a new coil that came with a diode installed backwards. It was not the filter.

I am doing a cab swap now and will install a new filter. I’ll post pics when that’s done.
