Preliminary Testing

PERFORM BEFORE BEGINNING SYSTEM DIAGNOSIS
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 GAGES Fuse 9 for open.
3. Check that the Generator connector and Generator "BAT" terminal are both clean and tight.
4. Check that the Battery connections are clean and tight.
5. Check Generator belt.
^ 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 (refer to "Troubleshooting Procedures"). Diagnostic Aids
^ Refer to System Diagnosis.
