Alternator?

[lifelongslacker]

First of all, I do not own an H1 (unfortunatly). But I would like to know how it is that your altenators do not short out when wet?! Are they sealed or just mounted in a really good spot?
Thanks.

they're not sealed its just the same alternator from a 3/4 or 1 ton chevy van. the whole engine, turbo and all are from the g-vans. most hummer owners don't know that their able to get most things from a chevy to replace the same more expensive part off their hummer

The alternator is mounted high and towards the back of the engine compartment. They are above the 30" mark that AM General specifies as the "water fording limit" for a stock diesel H1 (24" for the gassers made in 95-96).

The alternator is a standard GM unit, I recently got a replacement from NAPA for my rig.

During most fording deeper than 30", the truck may submerge to a level over the hood, but rarely is the truck in water long enough for the water to fill the engine compartment all the way to the top -- if it did, there would be some risk for shorting components out. Being a diesel, it does not rely on sparks to keep the engine running however, so you don't get the stalling effect that one gets from splashing a gas motor.

Hope that helps,
