| Post subject: | Alternator - Voltage Regulator, Sierra 91 |
Hey Guys, Recently on a trip away my voltage regulator failed, well I think it has. I checked the voltage over the battery and it is about +16v when the car is running. I went to the wreckers and found a 1990 barina alternator, it appears to be identical to the 1.3lt sierra one. I then changed the voltage regulator over to my sierra alternator. However it is still charging above 16v, any ideas?? I did not change the rectifier over The barina regulator might also be stuffed? Thanks guys, Dale |

Have you checked the sence wire that goes into the altinator for a voltage drop? I have upgraded mine directly from the battery thru a relay as it had a 2v drop across the factory wiring. |

Try another reg, you may have been unlucky twice Thanks Guys, yes the second voltage regulator was also stuffed. Grabbed another one from the wreckers and it now works. However it appears I have cooked both my main and dual battery plus the dual battery automatic isolator/charging thing. All fixed now. Dale |
