Working on a Prospector, and whenever I plug it in (power switch was bypassed), a few coils fire. The two that I've noticed are the right pop bumper (which is DC) and one of the chimes (AC). They're not locking on, they just pulse once and then are fine. I had the chimes off the unit to clean them and the chime plunger flew at least three feet in the air and landed on the ground outside the machine. Other two chimes and bumpers don't do a thing. Have no idea what could be causing it.... The playfield doesn't even have power at that point since the game over relay is off?
