are you able to id the locations of all the connections in the circuit
do you have a piercing tools, and T test backprobing test pins?
we can access the easiest connections first and move from there
i have 92 EVTM with nice diagrams, i can scan and send to you and we can go through it step by step
I will not spoon feed you,i will ask you what you think we should see before we test, so when we test, we can conclusively id the issue
