Slow engine cranking or low specific gravity of battery electrolyte may result from an undercharged battery due to failure in the generator even if the charging indicator light is operating normally.
Before beginning generator test in this case, perform the following procedures.
- Make sure that undercharged condition has not been caused by accessories being left on for extended period of time.
- Check drive belt for proper tension.
- If battery defect is suspected, refer to BATTERY DESCRIPTION .
- Inspect wiring for defects. Check all connections for tightness and cleanliness, including battery cable connections at battery, starting motor leads and ignition ground cable.
