Picked this up as a trainwreck back in the fall. Got it running and played it for a few months before I started teariing into it around the hollidays.
First thing that was noticed was the game went haywire whenever it seems like flashers were suppose to go off. Which is almost constant on this game. Even under the passanger inserts there are flashers. Game would try to pop a ball out of a saucer and turn on a flasher to correspond with it but instead another coil would rapid fire. Combine this with hitting something with the bell and you'd have 4 or so coils rapid firing and the bell going off. Game scared the hell out of everyone near it. Found an AC select relay stuck on the aux driver board. It basicly switches between a bank of grounds ( A bank or C bank) so that each transistor can fire 2 solenoids usually 1 coil and 1 flasher based upon A or C. Being stuck in A made it so when it was trying to ground a flasher it was grounding coils instead. Replaced that and I was good.
I had about 6 coils not working. The pop bumper coils were out due to a blown fuse because of some stuck close switches. Got that squared away easy enough. I had another coil for the catapult that was instantly blowing another fuse. Coil was fried and internally shorted. Transistor and pre driver both fried and locked on as well as a big tip36 on the aux driver board. Replaced all those and changed the coil with a close enough temp replacement.
So after a week of busy nights scratching my head and chasing crazy electrical issues the game played, but boy was it rough. The cab has dings and scuffs everywhere and the art was rubbed off in areas. Two huge worn out holes in the front from the biggest lock bar holes I've ever seen. Inside was stained and crusty and reeked.
Playfield is trashed and someone along the way pulled the Mylar but never pulled the glue and those areas just attracted more grime that stuck to the glue. Ramps are all cracked but work. Even the topper crumbled to pieces when I unbolted it from the head.
This will be an easier restore than highsped as I have a new CPR playfield for it as this one is way far gone to be worth the time to touch up. High speed was probably crazy with the time the touchups took me as well but it's all I could do at the time
