PowerMaster 140 Amp Alternator

Very nice alternator, well built, actually has a higher output than advertised. Each alternator comes with its own dyno specs sheet and mine was actually testing 160 amps output at highway rpms and 94 amps at idle rpms. Once installed my XJ stays at 14.9v, very nice

Great Alt. Easy hookup, Good fit and finish. Pully for "V" belt could fee better

Just put it in, so have not had a chance to see how it performs under load. Seems to keep my Red Top at max so far, even when running the winch. Easy to install!

It works good, install was easy as pie. I've heard pulleys need to be changed out, but that is easy as removing a nut.

I installed this to replace my stock unit. Handles my dual electric fans, radio, winch, driving lights. I run my dual flexalite fans after the jeep turns off and have never had a issue starting.
