Or home welder however you want it. I found this while I was looking for instructions to use a transpo d7044 alternator adjustable voltage kit for my tractor delco 10si alternator. I may add one of these to my tractor set of implements as I don't need a bobcat very often around my place. I'm hoping to use the pto.
