I am still have several issues but I think I am closer to solving the mystery. I sent the controller to RFF to rebuild/reprogram as I think it is one of the issues but the other is this;
I tested the contactor and following the manual procedures it shows as bad.
Question
Can I use any 72V contactor. I found several on Amazon prime for 100 and the GEM replacement is 280.00
Has anyone used an aftermarket contactor? Luck? Recommendations? Issues?

I have used three or four of these - they work great.

Only once per car, it has been four different cars over the years.
