Hey all,
First-time poster here with a quick question. I'm trying to fix up my 1987 Gottlied Diamond Lady with System 80B. I'm trying to locate the fuse for the playfield lights. I already found a bank of 8 or so fuses under the playfield, tested them all, and replaced the ones that were bad (now my drop targets work, etc.) but I have no playfield lighting at all (I do, however, have GI lighting). Any idea where that fuse is or what else could be causing the problem?

Thanks!!

Note: Pretty much everything else on the playfield SEEMS to be working, except the joker laugh that's supposed to emanate when you hit one of the playfield targets.

Turned out to be a bad bridge rectifier.
