I cleaned every connector on the 4 jones plugs in the backbox, and also the two on the bottom panel. I followed CFH's advice for cleaning them, using a wrapped 400 grit. I also inspected them and saw no disconnected wires. Bummer, no difference in the symptoms.
A ball in play will not score any points or activate chimes no matter what it hits, with the one exception of the joker hole on the right side, which will score 1000 points and ring the chime. The pop bumper and slingshots activate, flippers too. The right side middle lane will award and open the shooter lane gate correctly (gate is right outlane).
The game is not tilted, but the tilt still works properly.
how I test:
Turn on (Q and U start holding)
Push start: reels reset, targets reset, motor spins and stops.
Playfield is up, so I manually activate the outhole switch from underneath, which pops the coil. Then I activate the switch under the apron to simulate the ball rolling over it on the way to the shooter lane. I think this completes the start sequence of putting a ball in play.
Push drop target or pop bumper to test. Coils fire, but no score or chime.
Any other advice? I tried to read the schematics to see what is required for 10 points & chime, or a drop target to score and chime, or slings. Pretty much everything it seems have the Q and AX relay in the circuit. Is there a way to bypass these to maybe confirm they are not faulty?
I can manually activate the 10's or 100 relay and it works correctly. Same for the 500 or 3000 relay on the bottom panel. So, what is upstream from those that makes them activate, other than a target?
thanks again for any help.
