Alternator problem-
1 With a voltmeter measure 28 volts at the BAT terminal on the ALternator.
2. Measure 28 volts on the field terminal of the Alternator.
3. Make sure the 40 amp circuit breaker is not out.
4. With a light look into the side of the alternator (you can seen the cooling fan) and make sure it turns.
If there is no voltage on the BAT terminal the 40 amp circuit breaker is blown.
If there is no field voltage the regulator is U/S.
If it does not turn the drive is sheared.
If all of the above is ok you have a U/S alternator.
Hope this helps
