I have been having some difficulty with my alternator getting full of mud and not charging the battery to my truck. The last two times I have been out we wheeled all day and the alternator is fine for a while but both times the alternator has stopped working about half way through the day. The first time i had the alternator rebuilt and the second time i decided to take it apart and figure out what the problem is. Mud is getting between the brushes and the armature causing poor contact and hence impairing the alternator's ability charge.
Does anyone have any good tricks for keeping mud out of the alternator besides staying out of the mud. I don't really want to have to rebuild the alternator every time I go wheeling. i have had some ideas about wrapping the alternator in something to keep mud out but I was wondering if anyone had any other ideas that would be helpful.
Thanks everyone

Dont wrap it...it will burn up.
Why dont you think about moving it up higher on the engine instead of down real low where toyota decided to put it. Also you can try to fab up out of some thinner gauge steel a sheild for the alt. Kind of something like the u-joint/cv joint on your front d-shaft where it comes out of the t-case.
You could also seal up your engine compartment a lil better so mud doesnt come in as easily. Outdoor pond liner works well to fill the gaps. If you like to mud your rig, seal it up tighter then a can of beans. If you do seal everything up you might also want to convert to a electric fan and cut it off durring mud runs or deep water holes. Also they enable you to pull more air to the engine. I would suggest in a hood vent of some sorts, (scoops, cowl inductions, ect) to let the hot air escape.

Relocation seems to be in your best interest.
high and dry....
Alternate solution?
Get a spare.

well i had the same problem, so i made some rubber flaps to cover all the gaps between the frame and body inside the wheel wells, (you could look over my tires and see the engine alittle) so i have rubber covering the gaps, and even attatched to the top of the control arm so now when im in the mud my tires dont spray my alt. with crap. give it a shot, its cheap and easy

skid plate should catch most of it, but as the fella before me said get an old mudfla[ and try seal up some leaks, youll never keep all the mud out but you can definately slow it down.....We had an old beater 84 or 85 I made a snorkel kinda with stove pipe, you know the ole stuff our grandfolks used to run out the window for the fire burning heater and piped it up, O dod it to keep water out but mud/water same critter....

it is good to seal up the engine compartment on a mud truck. one of the best things i have found for it is old inner tubes from big tires. they are durable. i used pop rivets to secure them to the inner fenderwells. they work well. you should also upgrade to a GM alternater if you can.
