SVE 130 Amp Alternator 1G to 3G Upgrade Kit
This SVE 130 amp alternator upgrade kit gives your 1986-1993 Foxbody Mustang more charging power for your accessories! 1986-1993 Mustang stock alternators suffer from small wiring and low output, and the power wire plug is prone to melt and even cause an underhood fire. Add under drive pulleys and running your accessories such as headlights, A/C or the heat and you'll likely see the lights dim and the battery gauge drop. Throw an electric cooling fan in to the mix and the stock alternator simply cant keep up. This kit gives your Fox Body Mustang the extra charging power it needs to keep your electronics running smoothly!

More Output Power
Our 130amp SVE alternator is 100% brand new, no core charge, and carries a lifetime warranty. This alternator is from the internally regulated 3G series, includes the correct pulley (installed), and produces 75-100 amps at idle when used with the stock crank pulley and the installed alternator pulley. The idle output of the SVE alternator meets or exceeds the peak output of the stock alternator! The SVE alternator is rated at 130 amps continuous output, but is capable of producing 160+ amps at peak. A dyno sheet, specific to every alternator, is included with every alternator to verify these stats.

1G to 3G Upgrade Kit
This kit is made specifically for the installation of a Ford 3G alternator on any vehicle where the stock alternator was EXTERNALLY regulated. We incorporate a new replacement external regulator box (as shown) to capture the proper circuit and retain the stock wiring harness along with our own 3-wire (3G Series) regulator plug. This kit allows the customer to retain the OEM warning lights and shunt type ammeter **. Installation requires replacing the stock external regulator with the one provided, installing the alternator and our 3-wire plug, then make one crimp connection from the original wires at the alternator. All alternator upgrades require a large (#6 or #4 gauge) wire be run from the output of the alternator to the vehicle harness.

Power Wire Kit
This is a complete kit to upgrade the main power feed wire from the alternator to the vehicle on most Fords. Basically, the OEM wire from the alternator to the vehicle was not designed to carry the added load of higher amp alternators. If you use the stock wires again or not, is your choice, but using this large (#4 Gauge) wire kit will add the safe carrying capacity needed for lengths up to 10 feet. It also includes noise suppression.

Output will decrease when used with underdrive pulleys by up to 30%.

Our SVE Mustang 130A Alternator Kit includes a new OE type attaching bolt and nut, voltage regulator plug, and a stator plug.

**Being slightly larger then most other Ford units, minor bracket clearance/modification will be necessary.**

**This product comes with a limited lifetime warranty!**

5 Stars   Problem solved!
By on 7/26/2014
Image uploaded by Fred G. My stock charging system in my 84 5.0 LX convert was only charging at 12.4 volts with no load and 12.2 with AC and radio on. After 2 alternators, 3 regulators and a custom wiring harness built, none of which solved my problem and constantly weak battery I decided to take a shot at this upgrade kit.

I have to admit it wasn't as cut and dry as the instructions say and there was a big problem with the new alt constantly pulling power from my batter till it drained. This was from following the instructions to the T. After calling the manufacturer PA Performance we got great support and quickly discovered the issue and a quick move of the green wire to a switched line on the ignition coil and the problem was solved.

The only thing I'm disappointed with is that the 4 gauge wire that came with this kit does not have the noise reduction and that was one of the reasons I bought this kit. I still have a hi pitched whine from the alternator coming through my speaker system which annoys the crap outta me. But the biggest issue was the weak charging system stock in my 84. Now I'm charging at 14.5 volts with and without a load. I powered up everything in the car, AC, Hi-Beams, Radio, windshield wipers, radio, amp, brake lights, Not even a blip in power loss. Great system. Just need to improve the instructions and supply the noise reduction power line with this kit.

Yes, I would recommend this item to a friend!

5 Stars   High Voltage
By on 6/23/2014
so overall this is a great alternator and cheaper then others on the market, if your buying this for you 85 mustang it can seem a little confusing, the instructions that come with it are for either a 1966 to 81 or 1986 to like a 1993 but one call to PA Performance got me straight. its pretty straight forward but the pictures and instructions and a little different then what the 85 alternator has on it, you make a slight clearance mod for the alternator to fit but you pretty much only splice one wire, swap out the voltage regulator with the supplied one and add the 4 gauge wire with 200 amp fuse to the B+ side of solenoid and you done. I checked everything with a volt meter as per instructions and it works great. my headlights and instruments cluster do seem a little bitter. also its recommended to add an aftermarket volt meter because the old one will not read the new higher voltage correctly, overall I highly recommend this upgrade, works great.

5 Stars   Excellent item
By on 7/25/2014
This should be a must have for any mustang guy out there. Your headlights and gauge cluster will not dim at night like the old factory one. Had to use my drimmel and a few discs to remove the access on the bracket but other than that it was a simple install. Took me about an hour to do from start to finish.

Image uploaded by Gary P. I bought this kit for my 1978 Mustang II restoration upgrade. I am not much with electricity, but this was super easy, even for my limited skill set. It worked perfectly with my 1978 wiring and the 1991 engine setup!! A must have for my next project, too.
