I have the above pinball and during game play the lights over the entire pinball will dim for a split second. What may be the cause of this and is it an easy fix?

Also it seems my plastics are very loose. Is there supposed to be any sort of rubber or washer under the plastics to stop the movement i am having. Does anyone who owns the game have the same issue?

Cheers.
 
Will check them out, thanx...do you mean the smaller individual lugs on the power board (unsure of terminology)? Would fuses have anything to do with this as well?
 
He means the wires attached to the plastic housings going into the Power Module, and the silver colored header pins on the board itself. I haven't seen a Bally of this vintage that didn't need the majority of the connectors rebuilt to function reliably. Get a bunch of Molex .156 and .100 housings and the same type of crimp on pins/headers and you'll fix your lighting problem.

There is also a small change that it could be a bridge rectifier on the power module or bridge rectifier or cap on the solenoid driver board that could be dying.

See http://www.pinrepair.com/bally/index.htm and follow the steps to make sure all of your voltages are within spec.
