Good quality!
I was skeptical about buying an alternator from Amazon but after installing it and driving around for 2 weeks, I have zero complaints. Everything works as it should and I bought an open box one for cheap. Power Master is 👍I drive an ‘84 Camaro Z28 with a 305

So Simple
Bought this for my 12v conversion and the 1-Wire was a great option. Simplified the wiring down to the minimum. 100a is plenty for this old Jeep. Most run less than 60a but I wanted some headroom so I can run some radio equipment, a winch and a 12v fridge. Installation was like any alternator. Just needs one wire to go to the battery and it's ready to run.

Well made.
Well worth the money. Solid output at any any rpm so far. Best alternator ive found in the last 4 years thats not chinese junk. All of the weird electrical issues ive been fighting are gone now. So worth it.

Great upgrade for SBC
Fit perfectly on my 70 SBC. It is an upgrade i should have done a ling time ago. True single wire connection. Does not require reference voltage wire to optimize charging performance per instructions included in the box.

First was DOA, second one works
Bought this for an 85 Grand Wagoneer with a 5.9L. Installation was easy and I tried using it as a one wire. No charge. Increased RPM, checked ground, and still not charging. Thanks to Amazon returns and reorder I was able to get the replacement two days later. Installed again, and this time I'm getting 14.7-14.8 above idle. Hope it lasts.Update 3/9/2020 Six months later and a total of around 500 miles driven on a sub 200HP truck. Alternator screaming bearing upon startup today after replacing battery. Alternator voltage jumping from 10 to 12 rapidly. Second alternator in 6 months. Should have bought one locally from a part store so I'd at least have a warranty.
