I just got my repatriated TOM this week. I bought it from Italy with only photos. I wasn't sure what I was getting myself into - and really, I still don't. I'm just going to take it one problem at a time.

First, I did a continuity test on all Fuses and all were good.

Problem 1: Power Driver Board LED 5 (+20vdc, Flashlamp Circuit, Normally On) is not On. I run the Flasher Test T5, and no flashers are working.

The backbox lights don't work either. I don't know if this LED out, is related to that.

Any guidance would be greatly appreciated. Thanks.

Quoted from UltraPeepi:

GI lights - check out this on Pinwiki : http://www.pinwiki.com/wiki/index.php?title=Main_Page ( not related to first problem )

Check the 20 volt test point on the power driver board. If no 20 volts, then dig into the power driver board to find out why, check the 20 volt bridge rectifier first.
