Hey all,
I have no GI lighting on my RBION. I have checked continuity between light sockets and J15 and that is good. I have tested the voltage from the transformer and is is good at 6v. The fuses are good, relay is operating and i have continuity between J14 and J15. By my logic, I should have lighting.
What am I missing here? Should I be getting 6v between pins 1-4 and 6-9 on the J15 socket?

That's something I did not try.

I am getting 6v Between 1-4 and 6-9 with the connector removed.

.7v between the same when the connector is installed testing the exposed metal with my meter. Can it be the molex connector?

This is what I have tried now. I unplugged the GI J15, attached alligator clips to the board and attached them to the GI string on the playfield panel.
No lights. This bypassed everything in the wiring and still no lights. I am getting 6v on the board connector and 6v at the end of my alligator clips.
Only thing I can think of, the voltage is correct but not enough amperage?

I can take an individual bulb and light it with my alligator clips in my hand. I can then connect the clips to the string on the back panel, nothing. Not even the tested good bulb I lit before.
