I'm stumped.
Bally Nitro Ground Shaker:
Issue: will not kick out ball to start play, game will start and can play if you place a ball in the trough.
New Alltek MPU
New Alltek SDB
Repined MPU
Repined SDB P1/P2 (flipper connectors etc)
Things I've checked:
Replaced diode on the kicker coil. Checked the coil and it reads about 12ohms, slightly over spec I believe it should be about 10.5ohm. All fuses are good, all voltages are in spec, both confirmed with VOM as well as Alltek SDB.
Solenoid test fires all coils except the outhole kicker coil.
Checked switch operation, it does register on SDB, also when you activate the switch the drop target bank resets (yellow wires from drop bank to kick out coil). I've confirmed continuity of yellow wire at the coil to the connector on the back box (repined as well). Confirmed connection from the grey wire on the coil to the backbox. Confirmed good 1a SB fuse under the playfield.
I'm missing something simple. It should fire, yet it doesn't.
I'm new to Bally, so not sure if things are different between this and Williams with regards to solenoid operation. All other switches, coils operate as should.
Note: Lamp board is out of the game as I need to repin those connectors. As I'm typing this it dawns on me maybe it needs to be connected? If so why would all other coils work in game play? For all intents it plays, just won't kick out a ball.
Signed no ground shaking, just head-shaking....
