and 15.0 volts.
Check out and correct the following faults before
replacing an alternator: —
If the customer complains of a charging fault,
although the warning light functions correctly.
If the regulated voltage is less than 13.5 v, check
the alternator as the fault may be due to: —
1. A defective diode.
2. Phase out.
3. Carboned tracks.
4. Defective regulator.
