I am issue with my 94 land cruiser. Last year we took it to a local off road park and after awhile the voltage light and all the other lights came on. I figured, crap my alternator is bad. We stayed on the trails for a few hours with out any issues, besides the lights on. I was even able to drive home. Since it never died, I assumed water hit either the alternator or wire. Earlier in the year I took the land cruiser to pick my kids up from school (school is in my neighborhood, maybe a five minute walk). The lights were still on but the land cruiser never died. If something got wet it should have dried... Any idea what the problem could be?
