davpal, 1.) You are not understanding me. While the metal case of the rebuilt one-wire alternator you purchased may have been made by Delco, they DID NOT make the "innards" that make it "one-wire". The regulator and diode trio setup are non-standard aftermarket parts. (Delco DID make BIG semi truck alternators that will function as one-wire units.) 2.) You admit you have to "REV" the engine to get the one-wire alternator to charge. This can be a real problem with some of the older machines, if they have a relatively small crankshaft pulley and a slow-turning engine that maxes out at maybe 1400 RPM's. In some cases, one-wire alternators won't excite even with the engine "revved". That is why I recommend the standard 3-wire units that begin to charge at low engine speeds. They will work on ALL engine applications, saving trouble, returns, complaints, and comebacks. 3.) That being said, I'm glad the one-wire units have worked well for your applications, but I would not recommend them as a "one size fits all" solution to ALL old iron alternator conversions. If they are so great, why did the OEM's go through the added expense of the added wiring to make a "3-wire" system???

You can never have wide enough tires or heavy enough weights to get all the traction you want … unless you own a monster tractor. U
