I'm very happy to know you're enjoying the upgrade to true parallel alternators!

Makes you wonder why Cessna didn't do it this way themselves, since they already had the parts and the design ready to go.

will this work for the older models?

Hi Mark,

Will your modification work for the 337A model as well? Mine has the two 30 amp alternators, and I have just replaced one of my voltage regulators and about to change the other...

These older planes have just 1 regulator for both alternators (the second one is just a spare), so one alternator is always carrying more load.

Thanks,
Jeff

JAG, your alternators would work fine with this system. It would require 337 field approval, just like all the other installs, but I've yet to hear of anyone being denied the 337, as its a simple and safe upgrade.

EDIT:

There would be additional wiring required for the older airframes like yours. This upgraded system requires each alternator to have its own dedicated voltage regulator. I don't know how the wiring was done by Cessna on a 337A, but you would need independent circuits to each alternator.

I hope this helps. Feel free to PM me anytime.
