Was driving last week and the generator light came on, went off, came on again, and then it stayed on.
Belt is on, VR was swapped with another I have around (and another is on the way), ground at the tranny is connected and good, battery charged and tightened, fuses 8 & 9 are good and new, spun to make sure they are connected. Voltage meter is showing 12 to 13. Anything else I can troubleshoot before I pull the generator? (IMG:style_emoticons/default/dry.gif) |

Check the voltage at the battery using a DVOM. Should be about 12-12.5V with the car off and about 13.5-14.2 with the car running.
If the voltage is low with the car running, then either the regulator or the alternator are bad. |
