This seems like a really stupid question but "stupid is as stupid does"

I want to Si spray the alternator to decrease the chance of frying it when mud bogging. Do I just douse the entire thing? Do I spray the the air vent/coil area as well or should I stay away from that part? Thanks

also where do you guys buy the Si spray because i am looking to do the same thing.

I just bought a can from autozone but any auto parts store carries it!

equivalent military coatings:

Mil C 81309 (QPL Approved) – Ultra thin, water displacing films where surface can be recoated. Type 1 used on metal during shipment, storage and in service corrosion treatment. Type 2 is used on moving parts. TYPE 3 is used on avionic equipment as electrical connectors, plugs, contact points. Available in liquid and 16 oz aerosols.

This is good stuff! Works on multi million dollar jets and helos. All avionics. After a salt water immersion or massive amount of salt spray we deluge rinse the affected parts with water then dip or spray the affected parts.

To waterproof the electrics and alternator...I recommend starting at the spark plug boots, and working back to the distributer cap, coating all the wires and connections as you go...and then continue from the cap to battery and alternator wires and connections....then, go from there, to where ever the wires lead to, fuse boxes, relays, etc.

Priorities if pressed for time....all spark plug related, battery hot and ground to frame/engine connections, and...for the alternator....you are hitting the connections, but also spraying right into all of those slots and holes where the windings and brushes, etc live.

I like to spray it, let it sit a bit (Dry), run it a bit (To expose new areas inside...), and hit it again.



The Mil spec stuff is top drawer....PepBoys, etc, carry Wire Drier and other varieties that also work, and are fairly equivalent.

I also use dielectric grease on contacts such as bulbs, in spark plug boots, etc....and anti-corrosion films on the battery terminals.

With the X, I've never had an electical failure or stall off road...that's not to say I couldn't, lord knows I've tempted fate a few times...but a stitch in time saves 9, etc.

I bought mine at autozone.

Thanks, that's what I wasn't too sure about.
