Switches & Instrument Panels: Testing: Ammeter

On Challenger and Sapporo, check ammeter fuse in box at left front fender panel. On all models, remove ammeter. Connect a 3.4 watt bulb (or 60 ohm resistor) in series with a battery and ammeter. If ammeter indicates about 6 amps, it is working correctly. Ammeter is a shunt type that normally passes one-thirtieth of the current being used in vehicle. Do not allow more than 1 amp to pass through ammeter.
