Howdy!
I booted up JP and got a message stating 4 balls were missing. Yet, the balls were all in the trough. I checked all the switches and they appeared to all work. No missing diodes, no unsoldered connections, all of them clicked. I went into diagnostics and also noticed most of the coils were not firing and none of the flashers were working. I checked every fuse in the machine (even those under the playfield) and they are all good. I pulled the PPB out and checked all of the transistors, resistors and diodes....all good. I did the test to check the relay but it did not fire (shorted a transistor on the board). Is this a bad relay problem? Or is there something else I should be looking for? Any help would be appreciated. I had just repaired the power supply for this machine earlier this year and everything was working great until recently.
Thanks!
