I'm a new Thorp owner, Bought it in a few pieces Not an electrician, your experience would be appreciated 1. New alternator has voltage regulator, should I remove the separate existing voltage regulator? 2. There is also an existing OVERvoltage regulator as well, does that stay? Thanks John |

Does your new alternator have an internal regulator? Is it a one wire alternator? Is it an aircraft alternator? I suggest you have only one external regulator and do not rely on any internal one. They are notoriously poor. Your new alternator with an external regulator should have built in voltage protection. The way over voltage protection works is that it senses an over volt condition and kills power to the field wire in a two wire set up. If that is not what you have, it won’t work. Cubes |

I bought a copy of Bob Knuckolls book called Aeroelectric. He walks you through it all. I was able to wire my entire plane based off his book and wiring diagrams in the back of the book. |

I think the internally regulated alternators are more temperature sensitive than externally regulated and they sit really close to the standard Lycoming crossover exhaust system. I have been running an internally regulated Plane Power alternator with dedicated cooling air directed at it for 3 years now without any issues. As with anything else on the aircraft, that may change on the next flight. |

I also endorse the Plane Power alternator. Over a thousand hours with no problems. I did add a field switch to cut it off if it acts up. |

Yeah, I don’t like to run an alternator without a way to kill the field. I installed a circuit breaker/switch in the Thorp. |
