Having problems with 1979 Bally Future Spa flipper relay.
Ok I think I've tried everything to get the Flipper Relay to activate when starting a game .
Changed Q15 resistor -test good
Re pinned all connectors on Driver board but not the mpu board.
The Relay fires when touched with Ground wire from cab .
The relay does NOT fire in test Mode.
I have switched the 6821 pia chips.
Only reseated the 6800 chip.
Both flippers work when I keep the ground wire held on q15 and I can see and hear relay fireand hold.
Game boots with all 7 flashes and goes into attract mode.
All other solenoids work when starting a game and all but Relay fire in test .
Finally ordered a new Relay still waiting to arrive.
Just hoping for more info that I can do to get these
