I'm on pinwiki.com looking up power supply parts I should replace if voltages are low. it has one for Low +5 and suggests replacing the following parts:
however, I got EXTREMELY low +12 on my Jurassic Park PS board, so what all needs to be changed out to fix that, or will the parts I change for the +5 going to take care of that too?
more to come!
Low +5v
If you have a low +5v, you'll experience game resets, especially when pressing the flippers during multiball. A 'shotgun' repair would be to replace the bridge rectifier (DB1, CM3501), C2 (100uf 25v), C1 (1000uf 25v) and TR5 (2N6057) on the power supply board.
