Hey gang,
Looking for the proper configuration and/or clever solution to replacing the spring on my PA-30's external power receptacle. This is a 1963 Twinco with the power receptacle aft of the baggage door. My spring is shot and I don't even think it's the proper configuration. The door can open 60% of the way without any spring resistance. Anyone have any methods for fixing the door without replacing the receptacle?

Thanks,
David

David: My thoughts would be to take the receptacle out and remove the hinge pin, then wrap the spring one more turn around
over what you have now.
It looks like your spring is still good, but if it is week or broken then just replace it with a new one.
Not sure about that cotter pin holding the spring in place... you might find that this was installed after the original hook was broken.
I would think that even the earlier ones would not come from the factory like that.
Anyway I think you could easily just unscrew the connector and have a closer look at what is going on.

Good Luck,
Gary

Every semi-trailer on the road has a connector plug (the one that is used to connect tail/signal/stop/clearance lights to the tractor unit) similar to what you (and I) have on our planes. There are several manufacturers of these plugs but the configuration on all of them is very much the same. Go to any establishment that sells heavy truck and trailer parts and I am sure you will find the spring you need. Trucks on my farm have receptacles made by Phillips, Pollack, Cole-Hersey (identical to the power plug lid on my plane) and one or two other makes. Keep looking and you are sure to find what you need. You can buy a complete receptacle, lid and all, for less than $20.00.
Hope this helps,

Don,

Thanks for posting this practical info.

David;
In re-reading my post I should have explained that the heavy truck receptacle will have a 7-pin connector inside which is of course completely different from what we use. But if you remove the innards (only one screw to be removed) you will likely find the housing and lid to be identical to what you need. Any questions feel free to contact me.
