im taking it to a local company to test my alt. if its not putting out what it needs to then the 250a will be in. with custom brackets and such. now. would it be easiers to swap the new one in or run duals. i would run the new one in place of the ac compressor. also. with the plug for the stock alt, 3 wires come out. but the plug on the mechman only has 2 that come out of it. what do i do.
