It's working great. I just installed it on my Toyota fj70 1990, with a custom made steel adapters at both ends to hold the alternator to the engine. I believe this Alternator is for American made cars, which fits the socket perfectly, it's not UNIVERSAL as described. Anyways, now its working and charging I will make sure the nuts doesn't screw themselves from engine shaking from time to time. I will add some pictures later.

El alternador no me funciono como queria. estaba marcando 14.5 v en relanti, pero al encender los ventiladores se bajaba a 13.3 v, se apagaban los ventiladores y regresaba a 14.5v. Pero tengo un alternador tuff stuff de 100 amp funciona mucho mejor pues cuando encendia los ventiladores de 14.6 v bajaba a 14.3 v, sin problema de baja de corriente. Pense que este Powermaster de 150 amp iba a hacere mejor pero no. lo tuve que regresar.

Alternator charges great and was clocked correctly out of the box for an 86 Chevy caprice. The pulley installed out of the box was a V belt pulley as shown in the picture. An 86 Caprice Classic Brougham 307ci engine has a serpentine belt for the alternator. The pulley from the original alternator fit on the new alternator and the belt grooves aligned correctly. The main electrical output stud is larger than the stock stud and required an adapter to prevent cutting the factory harness or drilling the OEM lug.Good alternator but not exactly a direct replacement. I would buy it again despite the small fitment issues.

This alternator replaced a junk (and I very much mean junk) alternator from LActrical. For my Jeep so I can power the radiator fan, headlights, heater fan, windshield wipers, stereo, etc.The alternator came with a test card showing the amperage output, and voltage output at different rpm ranges.As per typical with a covered fan it makes a little noise, but very tolerable. There is a little electrical whine, easily fixed with proper grounding circuit.From idle to highway speed this alternator performs perfectly. Where the LActrical alternator barely performed better than the stock 35 amp (and got so hot to the touch it would burn your fingers), this alternator stays cool even under full load.I highly recommend using the "3 wire" set up with the load sensing and field power wires attached.
