Causes:
- Generator or alternator not receiving enough power
- Bad voltage regulator
- Bad wiring or loose connection
Solutions:
- Check the voltage at the generator or alternator. It should be between 13 and 14 volts.
- If the voltage is too low, check the wiring and connections between the generator or alternator and the battery.
- If the wiring and connections are good, the generator or alternator may be bad.
- Check the voltage regulator. It may be bad if the generator or alternator is not receiving enough power.
- If the voltage regulator is good, the generator or alternator may be bad.
