Review on Alternator Tractor 1 Wire Groove Pulley by Jeff Kersey

I bought this for an Amish neighbor who has a furniture store. It controls the entire workshop via a linear shaft. I hooked up a Kubota 3 cylinder diesel engine originally used in a refrigerated truck. The original alternator had a lot of extra wires that weren't necessary, and eventually it started draining the battery. He installed it himself and it works great with a single wire connection.
