The manual indicates that anything above 1 ohm should be repaired for and open circuit, and any presence of voltage should be repaired for a short.
I think I may have a short. I don't see any strange looking wires at the harnesses. I can't see anything down the wires that looks burnt or exposed (although I haven't checked the whole thing). Anyone out there have electrical experience to know what some increased resistance and voltage would indicate?
I wonder if I have an exposed section of wire that is barely shorted to ground.
It is hard to say - but any voltage in a circuit makes resistance readings unreliable. To measure for resistance, you need an UN-energized circuit. That is to say, if you are trying to measure a circuit's resistance to ground, the circuit MUST be de-energized.
