After reading your response and several pages back in this forum, I'm feeling better about the gauge. Fast, free online quotes for your car repair. To calculate the voltage drop of a piece of wire, you would have to know the current flowing in the circuit and the resistance of the wire. Using a water analogy, the electrical current amperage is equivalant to the water current flowing through a pipe.

The approximation balance length is located. That would mean that any shunt is internal, and probably the lower Red amps display actually is really measuring millivolts across a built in shunt, dating service kanpur scaled to amps for display purposes. Wire it like a fiberglass car. Any input would be appreciated. Step Install the negative battery cable and tighten until it is snug.
