Resistor fire

Oh, I see, you were talking about measuring across the GP relay. I don't know why anyone would want to do that, unless maybe you were troubleshooting the relay itself. If it's working correctly, of course the input and output will have the same voltage when it's engaged. Can't be otherwise.

I've used this test to troubleshoot the GP relay more than once. It is a common failure point as it carries over 100 amperes and cycles at least 3 times on every cold start.
