Gents,



I have three contactors mounted on the engine side of the firewall,

along with a battery.  Everything else (regulator, busses, etc.) is

inside the cabin.  Is there any value in covering up my contactors, or

are they alright as they are?



Many thanks,



James

   Here's the firewall of an A36 Bonanza.

    with contactors, fuseblocks, current limiters, etc

    hung out in behind Continental and everybody.

    I think your electro-whizzies will be fine without

    extra-ordinary cover.

Thanks for that Bob.  Even after a couple of years on the firewall in

the hangar, the contactors are already quite dull.  They're not

corroded, as I put some Vaseline (petroleum grease) on them and the

various connections.

That Bonanza certainly looks pristine!  Is there a trick to keeping

everything so sparkling?

   I took that on the production line . . . so it's a sure

   bet that the 'shine' goes away after a few years. But

   shine doesn't help the electrons get from point-A to

   point-B. The gas tight joint and designing switching

   devices to meet service life in the proposed application

   side steps the lack of luster.
