Alternator!!!!!!

When you get the rectifier bridge out. You'll see why they call it a bridge. Look under the bridge and you can see the blown diodes. The wire pins burn off because of the solder connections. The new bridge the diodes are welded in. Curing the problem. A alternator with a few blown diodes can cause all kinds of electrical problems. One sure sign you have a blown diode is. Lights blinking. The diodes are what turns AC into DC current. AC current doesn't play well with 12 DC devices.
Boss, maybe you can do a how to thread and we can take the links and add this in the how to section.
Anytime Jon tuned my car he always commentred on how low my voltage was during the data logging, he commanded more voltage through the tune.

Jon and I had the same problem with my car. I had two blown diodes. Took some time testing to get all the bugs out of my car. Learned a lot in the process. This is just one problem i found. I'll post some more later. Car can be a handful sometimes. It has a few built-in problems. Once you get-em fixed it's one hell of a ride. Next one i build I'll get some pics and do a how to.
Do they sell an alternator with those upgrades already done?
I'm so glad I clicked on this thread. Thanks for the links Illtaketwlight! :beer:
Yes as soon as I start taking everything out of the car, and start dissambling the alternator I'll take pics and try my best to post and do a writeup of the dissambling/assembling and changing of the guts of the alternator.

Ok quick update I've taken out the alternator off the car, upon initial inspection the part that went bad on mine was the voltage regulator. One of the brushes got stock in the inside position and wasn't making contact with the rotor slip ring. Here's a link to the part that went bad on mine:F601HD Heavy Duty Voltage Regulator Brush Holder Assembly for 6G Series Alternators
Hopefully this thread helps somebody diagnose the issue before doing like me and go out spending money on new alternators and unnecessary parts. Note to self first diagnose the issue and then order the necessary items.
I'll keep you guys updated, either way I'll upgrade my alternator with the new parts because I don't want to be stranded for something I can take care of now rather than later. I'm also upgrading the output from 110 to 135amp thanks to the links provided earlier.

Thanks for the thread guys, my alternator took a dump, diode plate was shot, but ordered all the parts for the full rebuild + billetshops pulley.
On initial start up I got the charging system indicator light on again, then the abs light, went and cleaned the battery terminals with baking soda , and no more charging system light.
And for sure, damm alternator removal is a chore, good time to replace the sway bar bushings with some poly ones...

Anyone use these?

As far as I know, that's PA Performance alternator. A correct installation requires an additional #4 cable from the charge terminal. See PA Performance's site.

I have a PA as do some of my friends.
Let me guess where you heard there were problems.
Not saying anything is perfect, and we don't sell them, so I have no skin in the game. But, when you find a "chicken little" story about a part, you can trace the source very easily. And, miraculously, the source just so happens to sell a "cure".
Caveat emptor.

I've burnt up a stocker and a PA alternator. I don't think the PA had a problem, I had some sort of short in my system after the motor was replaced.
I did replace the PA with a big Denzo unit a couple of years ago and have had no other problems.
This tip can be very helpful in your decision process...just know that this is good information.
Excellent info in this thread, just what I've been looking for. I ordered the HD Bridge Rectifier and a new 135 amp Stator today from the link provided. My alternator has not failed yet but I'm going rebuild mine with these parts so I don't have a problem in the future. $136.00 shipped.
