Ammeter Gauge: Testing and Inspection
Ammeter (Shunt Type) Test
Ammeter accuracy can be determined by comparing reading with an ammeter of known accuracy.
1. With engine stopped and ignition switch in "On" position, turn on headlamps and heater fan. Meter should indicate a discharge (-) condition.
2. If ammeter pointer does not move, check ammeter terminals for proper connection and open circuit in wiring harness. If connections and wiring
harness are satisfactory, ammeter is defective.
3. If ammeter indicates a charge (+) condition, wiring harness connections are reversed at ammeter.
