R1224 14V HARTZELL PLANE-POWER VOLTAGE REGULATOR
January 13, 2023

When my OEM Lamar voltage regulator failed I contacted Lamar Customer Service and was told they didnt have a replacement available for my OEM regulator. This Plane-Power regulator was offered as a possibility by Spruce Customer Service and it works perfectly replaced both the OEM regulator and the OEM over voltage relay, and is much more stable than the OEM Lamar regulator ever was since I have owned the airplane.

As advertised! The terminal block requires new ends on the conductors as they were smaller than OEM and the screws are very small. I installed this on a Lake LA4-200 along with a Planepower alternator. It’s working nominally.

Replaced the 50+ year old regulator and associated noise filter assembly in a PA28-140 with this regulator. Fairly easy to install with minor mounting changes, works as advertised.
