Night Rider EM
Bally, 1976Problem is playfield Control lamps work correctly sometimes, but majority of time control lamp lights are out.
GI lights work as they should.
Removed Jones connector clean male pins re-insert.
Replaced fuse holders, originals needed replacing anyway.
Check for bad solder joint on lamp PF bus wiring
When control lamps are working, playing a game they will go off.
Looking for ideas, not an EM guy
Check the game over relay for a normally closed switch with blue & white wires connected. Clean and inspect switch for a strong connection.
Right on the money.
Issue solved.
Thanks for your help directing, wire colors made it easier.
Greatly appreciated.
On EM pins should flippers make a buzzy sound?
Or is that an EOS adjustment
Buzzy or noisy flippers are usually a coil plunger stop problem. Machine gunning of the flipper is usually a end of stroke switch problem.
