I recently did some work to my Pinball Magic which involved removing the playfield to reach behind the ramp. Game was working perfectly.
Upon reassembly, any time that any solenoid fires, both flippers also engage. It is consistent across both sets of solenoids. Flashers, however are fine.
Of course, if I disconnect the flippers at the driver board the rest of the coils seem to operate as expected.
I have checked all my coils for a short. Diodes are not able to be tested in circuit, but I think it is unlikely that one just gave up the ghost.
Any ideas on what to trouble shoot next?
Thanks in advance!
