Need help identifying part number for replacement voltage regulator. I have a 1958 182 A That has had a alternator upgrade. Here is a picture of the current Motorola voltage regulator. I have done extensive research online trying to get a part number and have been unsuccessful. Please help!

Check in the logbook for which conversion has been installed if you haven’t already. There are several conversions over the years, that would be a good place to start. The A model I am working on for a friend has the Ford style electromotive conversion. It may be that one. Plane power offers a regulator that is designed to work with several different models, if your not a A&P find a experienced A&P to help you sort out the possibilities. The older aircraft sometimes drives us nuts trying to figure out what parts are installed.

Thanks for the input. I have looked in the logs and it lists the alternator install but no info on regulator.

I am sure there was an STC for the alternator install. The STC should specify the regulator. Er Ah I think

We just replaced the regulator on our new to us Cessna 172 XP with a Plane Power unit... there are several installation wiring diagrams that cover just about every alternator installation from stock to STC modified system.. not hard to install and relatively inexpensive at $230.00... they have an internal jumper for configuring either 12 or 24 bolt system’s. We bought a 12V one and swapped the jumpers for 24 volt for the XP..

I put the plane power unit in my 1963 182f two years ago and it has worked fine with no problem.
