Need internal schematic for overvolt protection PCB

[kevin]

Hi folks,

Anybody know where to get the internal schematic for the overvoltage protection circuit board on a '73 P337? It is not in the service manual, sadly...

Thanks,

Kevin

Kevin,
Back in 1997 I changed out the overvoltage sensing unit on my 1977 337 G (not a P). Part #C593004-0101, Sensor, New old stock. Paid $92.71 included shipping, from Prederred Airparts, Kidror, OH. Guy, old72driver....

Kevin,

I think if you'll give Cessna Technical Support a call at (316) 517-5800, they 'might' be able to assist. I say 'might' because I'm sure they're going to protect any proprietary details, you know, the "No Serviceable Parts Inside" trick.

On the other hand, they might surprise you. I had favorable help from Cessna in procuring a copy of the technical blueprint details for the cabin door assist mechanism.

Give it a shot and let us know what they say.

Thanks for the suggestion Skyking. I called 'em, they do not have a drawing, they referred me to the vendor, person who answered the phone thinks the info may be proprietary, but gave me the number of a person to check with on Monday.

We'll see.
