337 forms for 60 amp alternators and VR circuit

[Mark Hislop]

I already sent this to Tracy, but I thought I would post here in case anybody else wants the info. Attached is the form 337 for my aircraft for the installation of paralleled voltage regualtors. It's a very simple operation. The original VR's were replaced with the same regulators used in 400 series Cessnas.

The original Form 337 I got from CPA also showed the replacement of the orginal alternators with 60 Amp alternators. I didn't do that, so my From 337 doesn't show that information. Unfortunately, I can't find the orginal form. But as I remember, all that was necessary was to swap out the alternators and run a larger gage wire from the alternator to the buss.

Over the years, this installation has been trouble free for me. Both alternators are always "on line", and my volt/ammeter shows they share the load fairly well.
