A friend's TOTAN was resetting when both flipper buttons were pressed.  I was able to fix the reset issue by rebuilding the header pins on J103 on the power driver board as well as rebuilding a bunch of the burnt molex connectors.  Somebody had done a hell of a job mixing up wires on this thing.  I went through all the connectors and made sure it was all back to "factory" per the manual, but now none of the general illumination lamps work.  After working on this thing all day, I'm exhausted and stumped.  I'm hoping someone here can help me out.  Here's what I've done:
-Removed and checked all fuses with DMM
-Confirmed each pin on J103 has continuity through the correct fuse and corresponding pins on J105 and J106.
Here's the weird part.  If I check all those with the female connector on J103 disconnected, everything checks out okay with the DMM.  For example, pin 2 on J103 has continuity with fuse 114 all the way through to pin 7 on J105 and J106.  If one lead is held on pin 2 and touched to any other fuse or pin, no continuity exists.  Then, if I attach the female connector to J103 and do the same test using the back side of the connector, all fuses and pins on J105/J106 have continuity.  That's not normal, is it?  I traced the wires down into the cabinet and disconnected them where they meet the bundle of yellow wires coming from the transformer.  Testing this way shows the pins back to "normal" like when the female connector for J103 was off.  I'm so confused.  What am I missing here?
