Default Amp Gauge - Can it's range be modified

By the way, the current draw for the starter does NOT pass through the

No, but the alternator charging current probably does...

It's easy to modify an ammeter to make it read HIGHER (just put in a
shunt resistor across the terminals), but harder to make it read lower.
You'd have to replace the existing shunt resistor, probably internal to
the meter.

I solved the problem of small drain/large charging current by having
separate load and charging ammeters: a 10A for the load meter and a 50A
for the charging cct.
