I recently installed a Powermaster 1 wire alternator. I like it a lot so far. I don't have to rev the engine to get it to start charging. It puts out 14.4 volts even at the lower RPMs. According to their website, they offer some one wire alternators that will work with a charge light with the addition of a small harness. Time will tell if it is truly an excellent product.



I don't remember which brand I had but I had to rev the engine to about 1200rpm to start charging and the voltage would start to drop off at about 700rpm. The pulleys look to be the same diameter.
