Quoted from Joniano:
Follow up. You guys were right! Optos replaced fixed the incessant idol trigger. Regarding the magnet, after reading through the manual, at the very beginning, it states you need a 4A slo blo fuse for "this game only", not a 3A like the wiring diagram requests. The game was shipped with a blown 3A fuse in that spot, so I incorrectly kept running with that as it correlated to the wiring diagram. Plopped in a 4A fuse and the idol magnet plays perfect now.
1000 thanks to all you tech pinsiders!!!
The previous poster was absolutely correct. The whitestar era optos are often the culprit. Some folks will suggest reflowing the solder, but, replacements are so cheap, why bother. I keep a couple sets on hand as spares. Glad you got the problem solved. Ripleys is a blast to play, and a great "bang for your buck" pin to own.
