As is probably the case with many, my alternator is not the original and has a built in voltage regulator. The old voltage regulator is still in place and wired in its little compartment on the rear left. Can I remove that and cap the wires, or will it create some problem? |

Moe since you have the regulator built in the replacement you can remove the old one with no trouble, I would make sure no voltage is on any of the terminals and then,I just cut the terminals off and put a wire nut with tape on it just for safety sake gomer |

Great question....my question is how does one know if the alternator has a built in regulator.... Thanx. RCB |

When I removed my 4104 regulator I had to connect two large battery cables together that formerly went through the reg and were connected to two separate posts on the old reg. |

RC, Many of the self regulating alternators are called "one wire." Actually it should be one cable, but anyhow, only an output "wire." It makes its own field curent, as needed, and does its own internal regulation. If it has a field terminal on it, as well as a larger output terminal, it probably needs a reg. Gus would have had a generator, and the cables were connected to the reverse current relay in the regulator. HTH, George |

George, You have the system right. It has one wire to the batteries. The old system though is still in place. On the one hand, I think that it is not hurting anything so just leave it alone. One the other, I think that it is not doing anything so pull it out. The positive wire to it is still hot. |

Morning Moe, It sure sounds like you can remove your old reg. Also, there are probably two wires cut off near the alternator that came from the reg? The positive on the old reg should only be hot with the master on, if the reg has only three terminals, the hot one (probably marked batt or ign,) field, and ground. If you have the schematic, and want to be a real purist, you could disconnect the hot wire at the rear junction box, just read the schematic and make sure it doesn't feed something else in the engine room as well. It could very well feed the skinner valve as well as the reg! I don't have your schematic, and mine has the reg in the central junction box in the middle bay, so it is wired differently. HTH, George |

The regulator still has all three wires attached. I would cap them where they are and mark them for future use. My rear panel is partially blocked by the air filter and a bit of a pain to work in. Besides, having extra known hot and ground wires is like money in the bank. |
