I'm trying to diagnose a really weird issue on my BOP. Whenever the head motor is running, most of the flashlamps glow. Even if I unplug the head connector from the driver board, they still glow if I put the motor test on.

Tracing back the wiring from the schematic ... in theory the power for the head motor is a violet/orange wire on pin 2 of J107. I don't have anything connected there. Could someone check their BOP and see if J107 has 4 or 5 wires connected and take a pic? It's on the driver board, top middle, just to the left of the 2 bridge rectifiers.

thanks
