07SGT0517 Posted March 29, 2015 Report Share Posted March 29, 2015 Original alternator lasted to 135,000 miles... died on my way to work Wednesday. Surprisingly easy to replace. If anyone ever needs tips removing it feel free to PM me. Link to comment Share on other sites More sharing options...
LuLu Posted March 29, 2015 Report Share Posted March 29, 2015 Just replaced mine too, but only 58K miles. It was rather interesting to watch as it passed away. I have a ScanGauge II on the OBD port, and I watched my voltage die out as I was heading to a repair shop. Slowly, one by one, features failed. Radio, power windows, head/tail lights (it was after sunset) and so on. Finally, as I pulled into the shop, she went dead. Nothing. Simple install of a replacement, overnight charge, and all was forgiven. Good Lord, these alternators are not cheap! Looking at your sig pic...Is that a Carlisle sticker in the upper left corner of the windshield? If so, maybe I'll see you this year? Y'all be safe.

I was curious as I've never replaced an alternator on any car... I see $278 at Ford / Motorcraft parts, and $179 for an Advance Auto Parts unit.

I had mine changed at 1,200 miles just fried the end connector , I watched s the mechanic change it , not an easy job to do , he had a hard time getting it out .

roblectric Posted March 29, 2015 Report Share Posted March 29, 2015 Replaced mine in an attempt to resolve some diag codes that ultimately led to a motor replacement. It was a little tricky wiggling it out of there without removing the throttle body, but it was doable. Went with a PAPerformance alternator Link to comment Share on other sites More sharing options...

twobjshelbys Posted March 30, 2015 Report Share Posted March 30, 2015 I seem to recall that the Shelby parts group had a beefier alternator. Link to comment Share on other sites More sharing options...
mhr1961 Posted March 30, 2015 Report Share Posted March 30, 2015 If I am not mistaken Shelby (SPP) never offered a “beefier” high performance alternator for the 4.6 liter Shelby GT/Mustang GT Platform. They did however make an alternator for the 2007-2008 GT500 platform and it is still available from SPP but I don’t think it is applicable to the 4.6 liter SGT.

Jer Posted March 31, 2015 Report Share Posted March 31, 2015 We did offer one for the 4.6, a beefier unit made for and branded for Shelby by PA Performance. I don't see it on the website anymore (surprise, surprise). BTW, changing them is easy unless you have a Whipple. THEN, it's a bigger project!

07SGT0517 Posted March 31, 2015 Author Report Share Posted March 31, 2015 I went with the Black PA Performance alternator from American Muscle was $289. Just replaced mine too, but only 58K miles.

americaniron Posted March 31, 2015 Report Share Posted March 31, 2015 How 'bout a Whipple with a 10 rib setup...... 10 rib.JPG I know right. I have the Steeda 10 rib setup, and had to change mine last year. It would be easier for me next time now that I've done it, but still a little bit of a pain. I see why they made a part of the bracket to be removed easily. Link to comment Share on other sites More sharing options...
2007_Shelby_GT Posted April 1, 2015 Report Share Posted April 1, 2015 My alternator went south when I installed my supercharger at around 30K miles! With the Edelbrock S/C, you relocate and reorient the alternator, so it's facing toward the firewall. On the third test run, the alternator shaft gave way, causing the alternator pulley to rub against the engine head and creating a very worrying mechanical noise that sounded just like something had gone terribly wrong with the engine! With investigation, I found the issue and replaced the alternator with one from Autozone and all has been well since! Sam Link to comment Share on other sites More sharing options...

Alternator, round 2: After I charged the battery after replacing a dead alternator, the battery went dead! No crank over, just ticks, the battery showed 8.4 volts. Parked the evening before. I was out late, so, heater blower, radio, GPS and head/tail lights, occasional turn signal, loaded up the discharges for about 2 hours of highway driving. WTF? Charged it overnight again, drove it about 10 miles the next day and parked overnight again. More ticking the next morning, 8.1 volts on the meter this time. Called the shop, "bring it in" he said. I did. He asked "where is the car?" At home. "I need the car". No you don't, just test the battery? He did, it was shot, less than 4 volts by now. I bought it there 06/13, Motorcraft, got full replacement on warranty. I should have remembered that when you blow an alternator, there could be collateral damage. I wasn't pleased with the repair bill on the alternator, but I presumed that the system and battery was tested in that repair. Why shouldnt I? Could be a chance to sell other repairs, yes? Nothing important in this note, just a reminder about collateral damage. Y'all be safe. Link to comment Share on other sites More sharing options...
