    The finger is bad at the back of the circuit board?

    It's time to take the multi meter, kick on high beams, and follow the voltage to the indicator, I think.

    Looking at the EVTM again, it indicated a bad headlight switch could be the cause of a 'group' of IP lights out.

    I installed a new headlight switch, but no change. Still no hi-beam indicator.

    Not sure if I'm capable of tracking the voltage, but we'll see. I'm still thinking something in the IP or some sort of IP relay or distribution module, but I haven't found it in the manuals yet.

    Might be time to try another entire cluster...

    Success!

    I finally found the problem after pulling the IP gauge cluster completely out of the car for inspection.

    The printed circuit flap in the left side connector was folded back and not making connection on seven leads. Putting the flap back into the socket corrected the high-beam indicator along with other warning lights that weren't working at engine start-up.

    I guess I should have connected the multiple warning light issues together earlier. The overlap between that and the high-beam switch not working kept me focused in one direction when it was two unrelated problems.

    Now I can get the SC out for a drive. Thanks for the suggestions along the way.

    Glad to hear you were able to find the problem. As most of us here know these cars can be extremely frustrating at times, but when they're right, they're sweet.
