My altenator is going out on my K2500 GMC 4x4. I think the extra load from the Meyer angle plow helped it along. I tried the auto stores and the biggest ones they sell for my brackets is 65 amp. I can order 1 from a shop that is 95 amp for twice the money which I dont mind if I need it. My truck is straight with no air cond. It has 2 new batteries totaling 1600 cca. The electric shop recomends the 95 amp. What do you folks think?....mick
