I will check this when I get home this afternoon. Good idea.
follow the traces on that resistor and see which plug pin it goes to, then see if you can identify which wire in the car it goes to, this will give some direction....resistors don't pop for no reason, and you said it....too much voltage...
There is only one resistor on the board. I looked at the underside last night, albeit not super closely, and the traces looked ok, which is unfortunate in a way because if one was clearly fried it could steer me.
just a thought.....since you have your meter out check the voltage at the battery when the engine is running......just to make sure it's not overcharging....
Unlikely, but about 5 seconds to test, so I'll do it.

In addition, I need to find something that says what each blade on the harnesses is connected to. Then I need to do the continuity testing by touching one end of the multimeter to the blade, and the other to the end of what it connects to- if it doesn't beep, something is amiss, right?
