> The factory used in-series, full-current flow Ammeters. By that, I mean there were no parallel current shunts that proportionately divided the current flow. An ammeter isn't likely to fail, but after 40 yrs, I'd first start be inspecting and cleaning all the wiring junctions and connections. You can easily bypass the meter by safely joining it's wires together. You could easily test the ammeter, by taking it out of it's circuit (remove the wires from it) and then testing it with a VOM or test lamp in circuit. If the ammeter won't pass current to light a small test bulb and it's needle doesn't deflect under load, then it probably is bad.
