General Inspection
Ensure battery posts and cables are clean and tight. Check drive belt tension. Ensure connections at generator, regulator and engine ground are clean and tight. Check fusible links and replace as necessary.
Turn ignition on. Ensure charge warning light operates. Check bulb and circuit if necessary. Start engine and verify charge warning light goes out. If warning light goes out, see AMPERAGE OUTPUT TEST . If warning light does not go out, see VOLTAGE OUTPUT TEST . There are 4 conditions that can cause charge indicator light to come on:
- No Generator Output
- Overcharging
- Generator Output Wire Open
- Voltage Sensing Wire (Terminal "A" Circuit) Open
Check 120-amp ALT fuse and 10-amp ALT fuse located in engine compartment fuse box.
NOTE:
Low state of battery charge may occur on vehicles operated under frequent stop and start conditions in high temperatures, coupled with high electrical loads. A new pulley and belt kit is available from manufacturer to correct this condition.
