Switches, Gauges & Instrument Panels: Testing: Gauges: Ammeter

Turn headlights to "ON" position and ignition to "OFF" position. Meter pointer should move toward the "D" or discharge side of the gauge. If no pointer movement is noted, check the following: Rear of meter housing for loose connections, printed circuit connections, multiple connector at printed circuit. If connections are good replace ammeter. Should ammeter pointer move toward "C" with lights at "ON" position and engine off, ammeter connections are reversed. This is most likely to occur in an ammeter system that uses a wiring harness rather than a printed circuit.
