Started the car (72 2.0 L) this morning to go for gas. Alternator light stayed on for about 15 seconds after engine started then went out. Restarted the engine after getting gas and the light went out. Returned home no issues. Restarted engine after about 30 minutes. The alternator light came on and would not go out. Drove around the block and light remained on. Checked charging at battery NO charging.
2000 miles on new belt, new Bosche alternator,and new Bosche voltage regulator. Alternator wires properly plugged into the relay board. Belt properly adjusted. Transmission ground strap clean and tight. Help needed. |

You can check the alternator in the car by disconnecting the VR and shorting the D+ and DF wires together from the alternator. This is equivalent to the VR asking the alternator to provide full charging. If the alternator is ok, you should see 16V or so on the battery.
BTW, the fuse you want to check is S9. S9 also powers the oil warning light so if that light is lit when you turn the key on, then S9 is ok. |
