What's the brand name?



It was a Lamar. I didn't write down the model number. It was for a 14V
aircraft, probably a Piper, meaning that the regulator sinks the field
current.

Piper electrical systems source the field current. The other side of
the field winding is connected to ground.
My Comanche regulator grounds the field wiring. I thought most pipers
were that way.
