Re: Where's the shunt?
As you can imagine Ed, the ammeter isn't a highly calibrated peice of equipment. Variations in the 10 gauge wire resistance etc. can contribute to miscalibration. When guys upgrade thier charging system, they often replace that 10 gauge wire with an 8 gauge wire to handle the additional charging current. As a result, it's resistance decreases and the ammeter becomes less sensative.
