IDLE TEST RESULTS:
1. HIGH CHARGING VOLTS WHEN TESTING AT IDLE
The voltage output from the alternator to the battery exceeds the normal
limits of a functioning regulator. Check to ensure there is no loose
connection and the ground connection is normal
If there is no connection issue, replace the regulator. Since most
alternators have the regulator built-in, this will require you to replace the
alternator. The normal high limit of a typical automotive regulator is 14.7
volts +/- 0.05. Check manufacturer specifications for the correct limit, as it
will vary by vehicle type and manufacturer.
2. CHARGING SYSTEM NORMAL WHEN TESTING AT IDLE
The system is showing normal output from the alternator. No problem is
detected.
3. LOW CHARGING VOLTS WHEN TESTING AT IDLE
The alternator is not providing sufficient current to the battery. Check the
belts to ensure the alternator is rotating with engine running.
If the belts are slipping or broken, replace the belts and retest. Check the
connections from the alternator to the battery. If the connection is loose or
heavily corroded, clean or replace the cable and retest. If the belts and
connections are in good condition, replace the alternator.
RIPPLE TEST RESULTS:
1. RIPPLE DETECTED NORMAL
Diodes function well in the alternator / starter.
2. NO RIPPLE DETECTED
Ripple is not detected.
3. EXCESS RIPPLE DETECTED
One or more diodes in the alternator are not functioning or there is stator
damage. Check to ensure the alternator mounting is sturdy and that the
belts are in good shape and functioning properly. If the mounting and
belts are good, replace the alternator.
