ok well thats good, the drive board fixed the travel issue, awesome
as for the T1P check? It's fairly easy after you get the buss bars off of it, you don't want to test it while connected.
There are 3 IGBT's, 2 of them (located on outside edge and middle) are the drive ones and the other (located on center most location of the panel rails) is the pump. There are a bank of capacitors on top of those connecting rails also that need to be checked.
i have a couple of pieces of info i can send you on how to check that, email in my sig.
