I have a newer 105amp alternator and 2 800cca batteries and my lights still dim/blower fan slows down,etc when ever I move the plow up or angle it. I'm assuming my alternator just isn't up to the task of handing my radio, heat, lights, warning lights, and other electronics when plowing. What is a good size alternator to get that will keep up with all the power draw and still not be worked very hard? I'm thinking of getting a custom 250amp but is that overkill?
