one of the best tricks i found was use motorcycle chain WAX it comes in a spray can and is very very waterproof, very cheap and easy to aply.
a good snorkle is a must for deep stuff.

and then common sence so you dont end up flooded in the first place.

What would you use this on? Does it help with keeping water out of the cap?

Sorry if the answer is obvious.

basically i sprayed everything electrical on my car, if it could get water near it it got dosed in the stuff lol
just be aware not to get it on hot parts tho ok.

altho i didnt spray the altenator in it but put a quick spray on the connectors.
hope that helps mate

Thanks man. I have a 3" lift but I don't push the limits...thats why I asked about stock. I have had it about 3/4 up the wheels but didn't know if I should go any higher. I guess I'll call it about te limit. Thanks again and congrats on getting hitched.

Yeah I've seen the threads about it but I've never had an issue. Its the mud that kills them, not the water. Several guys I wheel with have said the same thing. The only times we've had problems is when we go through sandy water.

Maybe we've been lucky simply because we adhere to Murphys law, if it can go wrong, it will go wrong. So we bring a spare alternator and so far in a the past 3 years or so I've been wheeling I've never had to replace an alternator. Granted, its not a long time.

Sounds good, and easier than dielectric grease. Although on the larger ones I'll probably use both.

Just about anything that is sprayed on should be kept away from hot parts, but thanks for the heads up!

Thanks!

I've got a 3 as well, BDS makes it. I accidently dropped the entire front end in water, up over the hood. Somehow I got lucky and didn't stall, got out asap (less than 2 seconds and was out). Engine sputtered for awhile, but never sucked in water. There must've been a large enough cavity to allow air in the intake for the quick time she was under. Talk about a panic moment.

What I'd do is look where the lowest critical part is located. It should be the distributor, but I could be wrong. Anyway, mentally draw a horizontal line across your truck and mentally mark where it is on the body. Make that your "danger" line. I'm assuming its right around the top portion of the tire.

I've dunked mine in water, and she's still working. I think they guys who have the issues hit the trails more/harder and put their alt through more abuse.

Its still a good idea in my eyes. I don't need the AC, and it'd be much easier to get at. But, then again, if its not broke, why do the extra work?

Thats why I haven't bothered. I'm also mulling over the idea of putting in an OBA system in that location instead of those ARB or similar ones. Haven't decided yet and dont want to move the alt. if im just going to move it back. lol

Yeah, no sense in making more work for yourself.

If I ever do an OBA setup I'm going to attempt the AC conversion. If that doesn't work I'll go with something else. But right now I've already got an ARB compressor, just gotta get the $30 refil kit.
