1. how "water resistant" are alternators? i've seen pictures of isuzus playing in water. do they escape unharmed or are they sure to have electrical problems?

Most alternators are not waterproof, unless you get into the marine realm. Also, most alternators can handle some water with little problems, but...most water off-road is full of sand and silt. Those kill alternators very quickly.


Good luck,

Be careful there too. Most marine alternators are sealed in the respect that they don't spark. This is key because of the fumes that can build up in the engine compartments.

Normal "Marine" alternators aren't any more waterproof than the standard automotive alternators, they just cost 3x as much. Some of them are higher quality and are made from corrosion resistant materials, but like in the automotive world, there is crap available so be sure to check.
