The alternator circuit is exactly as you described (so long as your alternator has an internal regulator), its appears you have a duff new alternator. Is it a recon or a Bosch new one. cheers |

I agree with Jim, it needs going on a altr rig to test it (w/lamp is through the rectifier pack sounds like a diode has failed). cheers |

That was my thoughts, just trying to convince myself that ist was a duff unit, especially as its the same problem as the original unit |
