I searched all day, but didn`t find the answer I was looking for. Is there any reason why a 1 wire alternator can`t be used on my truck? I have a short somewhere in the part of the harness that connects to the alternator. Sure I could take the time and rewire it, but I would rather use a 1 wire setup. I know that they have drawbacks compared to a 3 wire, but is it bad enough to keep it from being practical? My charging system doesnt work at all, so anything is bound to be an improvement. Will it keep the battery charged? What amperage do I need? Thanks guys.
