i am not trying to high jack but it seems a lot of in the know people are on this thread just looking for help..my high out put alt is slowly putting less volts out it use to put a strong 14.6 out now it is putting 13.0 and nothing higher i charge the three batteries on a regular basis and have checked all the ground and hot leads..i have done the big three, three runs of 0 gauge wire for hots and grounds..i even went as far as putting a new regulator and brushes in it..it is about 3 years old it is a 240 amp alt..do these things just wear out after time and there is no hope left for them but to buy a new one?..i will contact the builder after i get a little info from you guys any help on this would be great thanks..
