Repairs and upgrades for the charging system

Calibrated the shunt against a 130 amp load each way. Get full deflection of the OEM gauge @ 130 amps. Of course full fielding the 37 amp alternator on the vehicle right now gives about 15% needle deflection on the stock instrument - rather than full scale. Still shows charge & discharge, just not so violently now.

The shunt could be made to take less (or more) of the load easily enough. I can do one that is 50% of full scale @ 37 amps.
