Took a 3 hour drive to Knoxville today. I watched the volt gauge. Seemed to be irratic. Hung at 11.4. But would jump to 13.5 for a short time them back to. 11.4. G lite was not on during the drive. After a short stop the re start is when the lite stayed on. Guage still at 11.4. I gotta get home.
Auto zone has a voltage reg. Is this a typical symptom of the easy to replace VR? |

Beware conducting this test. I took 45 - 60 seconds before fire started in the alternator wiring loom.
My readings were as follows Idle without any drain Rev 2000 18.2v Idle 16.7 v Lights on idle 14.58v rev 2000 17.5v Brake light on with lights Idle 14.09v rev 2000 16.9v |

Beware conducting this test. I took 45 - 60 seconds before fire started in the alternator wiring loom. Excellent point. This "Full on" alternator test should not be done for a long period. The goal is to see the alternator give full voltage when the VR is shorted. Once a healthy voltage is observed, the test can be concluded. |
