Works Ok
I’ve had this alternator on my 1997 F350 for almost a year now. It works ok but the voltage regulator is inconsistent. It noticeably fluctuates even when little things are turned on and off and sometimes on a long drive the voltage will be lower for a while and then comes back up to normal for no apparent reason. I have good Blue Top Optima batteries and all my connections are clean and corrosion free so its definitely the alternator that fluctuates. At this point I prefer the Powermaster alternators that I run in my other high demand vehicles
Great product
Solved my battery light coming on issue. Quality part very happy with the purchase. Wanted something stronger and more reliable then what autozone can offer.
Great upgrade for my F350.
This high output alternator bolted right on to my 1997 Ford F350. Now I have plenty of power to run my sound system, retracting steps and lights.
