Alternator: Testing and Inspection

If charge indicator light works abnormally, perform the following test procedure:

1. Visually check belt and wiring.
2. With engine control switch ON and engine stopped, charge indicator lamp should be on. If lamp is not on, detach wiring harness at generator and ground "L" terminal. If lamp lights, generator is faulty. If lamp does not light, locate open circuit between grounding lead and ignition switch and check for a faulty bulb.
3. With engine control switch ON and engine running at a moderate speed, charge indicator lamp should be off. If lamp is not off, detach wiring harness at generator. If lamp goes off, generator is faulty. If lamp stays on, check for grounded "L" terminal in wire harness.
