Repairs and upgrades for the charging system

The shunt is 360 brass. Less conductive than copper.

.035 thick, .490 wide, and .890 active length.

I started wider and reduced the width for calibration.

Ohm's law for parallel resistors will get you very close. The OEM ammeter is not terribly precise, I measured 3 different ones and got different readings.

Obviously you will need a Wheatstone bridge to measure the very low resistance ammeter & shunt.
