When I took my 914-6 out for a spin yesterday, I noticed that the voltmeter was only reading 12 volts instead of the usual 14 volts. The generator light was lit upon initial startup, but went out as soon as the alternator energized and then stayed off throughout the drive.
I am surrently using an aftermarket transistorized voltage regulator, but kept my original Bosch can regulator. Does anyone have information on how to check the voltage regulator function. I've used some very fine sandpaper to clean the points, but don't know if anyone has the info on adjusting the opening and closing voltages. |

Hey George
I drove my car occasionally for two years not knowing that my alternator was not charging. My Optima battery sometimes needed to be charged but I thought it was from sitting for long periods. The charge lamp worked and would go out above idle. I finally discovered the no charge situation and removed the alternator (what fun!.... especially on a 6 !) and found the brushes were not making good contact on the armature due to a grey foreign material on the armature contacts. The rebuilder was honest and told me the issue. Cleaned, installed, no problem. 13.8V ! |
