Charge Test Results
Charging Normal
: No problems detected.
Charging Low
: Charging voltage is low; check alternator drive belt and/
or the alternator and battery connections. If no faults are found, refer to the
manufacturer’s documentation for charging system fault-finding.
Charging High
: Alternator output voltage is too high; it is likely that the
alternator’s internal voltage regulator is faulty. Overcharging will damage the
battery and drastically shorten its life.
No Volt Output
: No output from the generator or alternator has been
detected — refer to ‘Charging Low’ instructions above.
