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? |

The video does not really show the bent-ness of the shaft. Maybe it is more visible close to the end of the 30 second video. Between the bent shaft and the mis-aligned brushes the ALT failed after 14 months, maybe 8000 miles..... THE END.

Between the bent shaft and the mis-aligned brushes the ALT failed after 14 months, maybe 8000 miles..... THE END. About the shaft wobble, to check it you would have to support both front and rear bearings then check for rotation variation. If just supported by the front bearing, you may just be seeing the play in the bearing as you rotate. The misalignment for sure is an issue. It may have been that the one brush was slightly touching the other ring and causing the brush to touch both rings thus killing the armature current and causing the alternator to not produce voltage. You could try to adjust the alignment of the brushes and have the alternator tested at Autozone or other FLAPS. Seeing how you've got 14 months on it the rest of the alternator it might still be ok. |
