Quoted from jnauman:Coil was weak. Replaced and working fine.
Now I have a switch matrix problem. Column 6 is not working. In test mode power payoff, switch 65 shows closed, rest open, but none work in test mode. Switch looks fine, not closed, and diode is good.
Checked the boards and not sure if this is an issue or related, but when I got to pin 3 of J207 I believe and jumped to pins 1-5 of J209 coils would fire. Is this normal or even related to my switch issues?
As with all switch problems, the first thing to do is *disconnect* the playfield and cabinet switch connectors. If the problem remains, it's on the MPU board. If the problem clears, then it's on the wiring on the cabinet/playfield.
