Is the wire upgrade required to install this ?

This PA Performance Alternator can see up to 160 amps, and the stock wiring kit cannot handle the additional current. The PA Performance Premium Power Wire Kit utilizes, item 95312, to properly handle the additional current. https://www.americanmuscle.com/powerwire-0509.html

Just replaced my stock alternator that bit the dust with this PA Performance Alternator. Now my Shaker 500 constantly clicks even when the car is off so I had to disconnect the battery. Is this common when replacing alternators, or do I need to be looking elsewhere?

You should not be experiencing any of these issues after installing the PA Performance Alternator. We recommend taking the car to a shop so this issue can be properly diagnosed.

Helpful (1)

How many more amps does this alternator produce over the stock part in a 2006 GT? Thanks!

The stock Alternator produces 110 Amps while the PA Performance Alternator produces 130 Amps. You will definitely see a great increase in the charging capacity at all RPM Ranges.

Helpful (1)

would this alternator work with a Department of Boost supercharger kit alternator has been moved to the top right of engine?

This should work however, we have not yet test fit this combination ourselves at this point in time.

Hi been planning on upgrading my alternator since I have the shaker 500 and a 12” in the trunk with a Bama 91 oct tune will this affect it in any way. Just want to get more power to the sound system 1 answer

The tune would not affect the sound system, however, using a larger alternator will allow for more power output to help with the sound system.

Does this fit a 2009 mustang GT ? Product page only says 05-08 but just want to be sure. 1 answer

Why will this not work on a 2010 G.T? Does A.M. Offer an alternator for my car? 1 answer

Hey Randall, Unfortunately that alternator will not work for any 2010 model because Ford being Ford had made changes to the car that recreated the alternator. And at the moment we do not offer an alternator that would work.

My alternator is bad and I was looking to upgrade it to a higher amp. I believe the 2006 Mustang 4.6L alternator amps is 135. Can you tell me how this alternator would be an upgrade to stock? I currently have the shaker 1000 and will be upgrading the stereo in the near future. I also have the msd coil packs and spark plugs. 1 answer

The PA Performance Alternator is a 135A Rated alternator, but will operate in a range of 80 amps at idle to a maximum of 160A. The OEM Ford alternator is rated at 80 amps at idle and 135amps max. The increase in peak amperage can assist in powering more accessories, however idle amperage will remain the same at ~80a. The MSD Coil packs and plugs will not necessitate any additional battery or charging upgrades, however an aftermarket stereo may require upgrades, depending on the power usage of the stereo setup.

I am Having Headlight Brighten / Dim Issue. I Replaced my OEM Altenator cable with The PA 130AMP Altenator and upgraded Recommended Cable. This issue is still happening to me. Under Power (Driving) no issues, but when I am stopped and I REV the engine the Lights Brighten than Dim as the RPMs come back down. Obvious 1st steps check belt, battery, Responses appreciated for ANY Other Ideas or Similar Experiences. Thanks 1 answer

There are two main issues that could cause the lights to brighten and dim at idle. The first would be an under performing Alternator, or being underspun by underdrive pulleys. The second would be a weak battery, or a battery that is under the correct capacity for the car. I would start by checking alternator output at idle.

finally replaced with this PA unit

The original alternator went about a year after having the car. That ford warranty refurbished unit lasted about 4 years. Then I had to replace it with a local auto parts store unit. Luckily, I got the lifetime warranty version as it only lasted about 2 months. Fast forward 4 years, the dreaded 'check charging system' light came on - quickly had everything tested and it was the alternator. Always wanted to get this unit after the first one went - looks great, super easy install along with the upgrade wire.

Having issues

I installed the pa alt. on Sunday. Wife took it to work Monday morning with the heater on and the Idle would drop to about 400 and then jump up to 1500-2000 rpms. I am not sure about this alt yet since I am having an issue. It only seems to happen when the heater is on, no other time. The car ran perfectly prior to this (just had the charging system fault). I called AM and they said to call PA perf. Spoke with them and all they could say was: hmmm, not sure why it would do that. Couldn't give me anything!!! So far I am NOT happy. It only took a little while to install. I had issues with the stock battery post connector though, which added a few more hours to my install.

Works Well

My car threw a camshaft positioning sensor failure code, found a forum saying that was a common symptom for the stock alternator going bad (which was supposedly a known issue for 05-09 mustangs). So I bought this, installed it and it work great. Even fixed a couple other small intermittent problems I was having.

Awesome

Went through 2 reman alternators and 3 batteries on my 06. Finally decided to try a performance alternator and problem solved. I now get constant voltage at any RPM. Highly recommend this replacement if you installed underdrive pulleys.

PA performance quality

This is my third alternator, first two were refurbished from A local auto parts both of them died after 30 days or so. Spent the extra cash to get the PA performance one, took about 4 days to get to me from AM, packaging was ok.. everything looked good. Installation took about 45 minutes. Getting about 14.35 volts to the battery now, has a little whine to it when at idle. So far no issues. From the forums I have read that the 05-09 GTs have alternator related issues but with the PA I think I’m in good hands. The black finish is nice, I definitely recommend spending the money for this for the peace of mind. Thanks for the help AM.
