Quoted from arcadebeast:this thing is killing me. i bought a new rottendog driver board and still the same coil engages when game is turned on and stays that way, will not release ball for game start. so i disconnected every board and coil still stays engaged as soon as i turn game on.
Quoted from ChrisHibler:Monte Carlo has a large number of under PF transistors. Fish out the schematics to see if one drives that coil. The OEM transistors were 2N5875s. They seem to fail quite often. Pick up some beefier 2N5884s from Big Daddy Enterprises.
This is good ^^^^^^^ advice.
