## Description

Powermaster 7294 Alternator

Review: Good quality! - I was skeptical about buying an alternator from desertcart 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
Review: Powermaster alternator works, accomodate double pully switch over for Grand Wagoneers with AC! - Powermaster 7294 accepts double pully switch over from origional alternator on Jeep Grand Wagoneers (spindle is long enough). Double pully is necessary for Grand Wagoneers with AC (at least 86-91)! Dozens of alternators sold at autoparts stores and on line say they "fit" full size (FSJ) 5.9 liter Jeep Grand Wagoneers, but beware. Many will not accept the double pully from the old alternator and are useless. The Powermanster alternator was delivered next day by desertcart. Well packaged, has instructions, no core charge or return required, priced reasonably, and it's obviously more professionally produced. Others I tried were either defective or would not take the double pully. If you have Grand Wagoneer with AC, THIS ONE WORKS!!!

A: 100 Amp. Thanks - Tim.

**Q: Can I get this with a 2 groove pulley?**

A: The same as your stock, nothings different. Did swap out myself and I’m no mechanic!!!

### ⭐⭐⭐⭐⭐ Powermaster Alternator turns heads!
*by N***7 on January 8, 2024*

Purchased Powermaster 7294 Alternator. fits into my 79 Pontiac nicely. Make sure you send 8 gauge from power terminal to battery and ground the alternator also with 8 gauge wire. fits nicely with the march pulley setup and belt tension must be snug. Old powermaster alternator quit due to improper grounding i assume.
