Has anyone replaced their Delco Remy voltage regulator (the old
mechanical type for a 50 amp generator) with a new solid state
type by Zeftronics? CHief aircraft sells them, just wondering
what anyone's experience was.

Mine is old, acting up and charging too high. In the old days I
guess you could clean the contacts and so forth but I'd rather just
replace it.

I replaced the Delco-Remy's and paralelling relay on my PA-30 with
Zeftronics, and couldn't be happier. I used to stock a spare generator
and have to replace them regularly - once I installed the Zeftronics,
this came to an end. Guess they don't arc as much.

The installation instructions are dead simple, and they have
diagnostics that tell you what is wrong. In fact, the Zeftronics
regulators were my first experience ever with buying a PMA part (other
than an engine part) and being able to install it exactly per
instructions and having everything work without cutting, fitting,
adjusting, and generally messing with it. It's a good design, IMO.

I also discovered, by talking to their chief engineer, that there is
someone in this world who has a lower opinion of the FAA engineering
and certification people than I do.
