Well I do thank all for your suggestions but it appears I looked into this problem way too deep. I really feel dumb for not checking out the lights in the T-handle itself. I forget which TCTO modifies this, but there is a little piece of plastic that is supposed to slide between the top and bottom light bulb holders. Someone had removed it and uppon reinstalling they caught the ground contact on one of the bottom bulbs and had it jammed against the ground contact of the top bulb holder. So after three long days of troubleshooting and digging around in the 2-13, all it took to fix it was a flat head screwdriver. I'm dissappointed with myself for not catching that but I can guarantee it will be the first thing I check from now on. Thanks to all again.
