Reply to "Amp Gauge waving like a beauty queen in a parade"

I thought the wavey amp meter needle was because all the charging system current goes through the meter so it over-reacts to changes in demand and the voltage regulator actions. The fix is to make a copper shunt that goes between the two terminals on the back of the gauge. Size the shunt so it carries most of the load but some goes through the meter so it registers slightly. This dampens out the waving. Someone correct me if I got that wrong. I think decades ago I did that to mine but the years cloud the brain.
