Quoted from MaxAsh:Good connection from 2J12-1 to flipper button switch, good connection from the other side of the switch all the way through the various connectors. Switch continuity good, even if I hook up back at the board end to test when I close the flipper button switch. I can always re-pin the connector, just in case, even though it's testing good. 36V at the coil lugs on both working and non-working flippers. 3J3-4 showing 18V when measured to GND (half of the 36 at the coil lugs, interesting).
Definitely seems like a really basic setup, so where the heck is the gap.
Usually a bad diode on the coil will blow the fuse, right? But that's not happening. I do have a spare new coil, so I could always swap that in just in case. Or I could just pull that diode off the existing and test it I guess.
No Flippers and Voltage is arriving to the coils:
Check that the TILT relay is energizing on the driverboard in Test
2J12 Pins 1 and 2 the relay switches ground off and on to these pins
When relay is energized flippers are turned ON
Test flippers:
Ground can be added by jumper at 2J12 1 and 2 for checking flipper operation bypassing relay cut off
