hey there prentice
I have been reading your post a few things you might check are
1.check this item around the control system you should see what looks like a coil wound copper wire with a coating of laquer on it right near the diodes it is reasonably big one end of it will be bolted onto the heatsink check physically that the end where the eyelet is not broken sometimes they break but because the copper coil is quite stiff stays in the same position so you don't see the break
2.make sure that the line contactor is not dropping out when you turn on the ignition
3.make sure that the drive motor and cables are ok because the reason for the t fuse is a broken or loose terminal/cable
if you had had a blown fuse it would come up with the same fault
so if you had a broken motor cable that is the same as a blown fuse if you follow what I mean
4.finally make sure that the fw/rev contactors are seating properly as you need the back of the contactor to sit on its tips properly so when one contactor is engaged the other one is making the circuit on its neutral position.

hope this helps good luck
