Powermaster 57294 Alternator

Had a power issue on my Jeep with a AMC 360 and DUI distributor. Upgraded to this alternator and don’t have any more problems, it makes plenty of power for the engine, lights, and accessories. Power master has never disappointed me and their alternators always work, easy to install, and last through some harsh conditions.

If this alternator doesn't last but for the warranty duration, I'd be satisfied with my purchase! By far, it's a definite upgrade from the stock OEM version. I have LEDs galore both inside and out and couldn't run certain multiple lights at the same time. That is until now! And that's not even factoring in the sound system. At idle with 3 sets of spot lights turned on this thing had a 100 amp output. That was more than the OEM put out without any lights and going down the road. They have a customer for life right here!

Works well, fits as expected, keeps 14 + volts with all my off road and search lights on,After 10 minutes it was barely warm.Very happy with my purchase and it’s made in the USA, not some Chinese garbage.

This alternator looks amazing under my hood. I only had to change out the pulley from my old alternator. I've been adding modern conveniences to my 1986 GMC Jimmy and upgrading some things, and I was concerned about replacing the alternator with something not stock. I worry no more! This bolted straight in to the engine block and bracket as if it belonged there. I recommend this alternator for those who have a small block Chevy 350.

I believe I connected it correctly. It is not charging the battery. It's on a 1969 DeVille and has not been driven much at all; maybe 200 miles since installation. Sure would like support on this issue. I'll see what they have to say.

...Except for the fact that any of the old style alternators (no matter the amp rating) seem to be unable to supply all accessories at idle, in gear at a stoplight in the heavy rain when you need headlights, defrost on high (which adds the A/C), rear defogger plus my SPAL electric radiator fans. It will only give about 11 volts so the battery is being consumed rather than charged during these times. I even have all LED lights everywhere which draw a fraction of old style lamp bulbs. My attempt to solve this will be the smallest alternator pulley I could find which I have used on previous alternators to good effect--- that is, under the above conditions the alternator keeps charging and the dash voltmeter reads 14.5 volts the entire time, confirmed by my VOM at the battery terminals. It is like the engine idling an extra 500 rpm with the original pulley.

Installed this in my 68 Coupe Deville. Had to reclock it. Putting out over 14 volts steady at idle now. Bought a returned unit no issues. Will update.

It was a rough install. Lots of foul language, but works like a champ.

Exelente trabajo muy bien, voltaje arriba de 13v. Solo realice una pequeña adaptación ya que mi motor es un 231 y cambiaba poco la base

Easy install, works great, looks awesome!
