Troubleshooting Hints - Charging System

CHARGING SYSTEM
1. Visually inspect the hydrometer (built into battery).
- Green eye - Battery is charged.
- Dark eye - Charge and load test battery. If battery passes load test, refer to "System Diagnosis."
- Clear or light yellow eye - battery electrolyte is low. Replace battery.
2. Check IGN fuse.
3. Check that the Generator Connector and Generator "BAT" terminal are clean and tight.
4. Check that the Starter Solenoid terminal "B" is clean and tight.
5. Check that Fusible Link "F1" is undamaged.
6. Check Generator Belt.
7. Check that battery connections are clean and tight
8. Check that ground G2OO is clean and tight.

^ Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove "GOOD" in a continuity/voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a voltage drop with the system operational (under load).

^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.

SYSTEM DIAGNOSIS
Perform the Diagnostic System Check in Powertrain Management/Computer and Control Systems/System Diagnosis to make certain that no diagnostic trouble codes are stored in the Powertrain Control Module (PCM) memory. Stored codes can lead to misdiagnosis. Testing and Inspection
