You are WAY better of to actually learn what you are measuring with a conventional multimeter. Somebody is missing something here, I know not what. In this case even a simple test lamp might be better to find the problem
The power probe is both a multimeter and a testlight in one. Regardless i think you might be on to something with the body not being grounded. I have a strap to the engine but nothing direct to the body. Ill try that too. The car hasnt been on the road since 2012 from what i can tell, the original owner had really butcher’d the poor thing. So im not sure whats been removed. Like i said brand new wire harnesses. Also should i attach a ground to the rallye cluster?
