Help needed with Centipede Cocktail

[wakerlet]

All,

I know this a little off topic but I know a lot of you also repair games as well as MAME them.

I have a Centipede cocktail that plays blind most of the time.  I need to replace the monitor but while I'm doing that I might as well address a growing concern.  It appears that the coin door is charged, that is, when I touch it I get a mild electrical shock (like moderate tingling).  The cabinet only has a two prong cord (no ground).

Question:  If I replace the current cord with a grounded one, what will I need to ground in the cabinet itself? Will this solve the problem I have?

Has anyone experienced an issue like this?

Thanks for any help.

Todd,

The game should have a 3 prong cord.

Also note that some cabinets do this when missing the third prong, and others don't. And some cabinets have a 3 prong cord, but eliminate the third prong instantly inside the cabinet (actually that is WAY common).

Of course, if you live in a place like mine where it is all 2 prong, then that isn't going to help much, is it.

I had a Do! Run Run that did that, and I was able to get it to quit simply by increasing the connectivity between the various metal grounds in the thing. Luckily that worked, because it was a 2 prong japanese cabinet and I have a 2 prong house anyway.
