New batteries,voltage regulator, alternator,because they went bad one after another, now i have a 5 amp dran when not in operation draning bateries any ideas
Check the aux fan - notoroius for draining batteries. Also take out each of the fuses in turn and monitor the current drain to see which line is causing it. That will at least narrow it down to one circuit to chase through.
