Starting to get pissed....

[driller]

Driller have you used a PA performance alt yet? I heard they are quite stout unless you spin past a certain shaft rpm (16,000 shaft rpms).

I've had 2 of 'em from PA Performance.

I've had OEM, including the Cobra unit.

shouldnt the word "had" be replaced with "driller'd"/killed?
*g*

 

[driller]

Yep. I've killed the best or 'em.

I've talked to a local rebuilder who said he could rebuild them but without looking at them, he couldn't give a price or promise that they would last. I need to drop one off and see what the autopsy results are.

 

[ripped camel]

hmmmm...would changing the diameter of the pulley result in less shaft rpms driller?

I've been all over the map with this.

When I first put the underdrive crank pulley on I installed a smaller pulley on the alternator to bring idle rpms of the alternator back near stock. Worked slick for a couple years.

Then once I started toasting alternators hitting the rev limiter, I stepped back the pulley and suffered through low voltage at idle. Then with the latest mods resulting in higher rpms, I find myself with the same problem but now with the stock diameter alternator pulley.

I'm going to get one of the PA Performance alternators rebuilt locally and probably go to a compromised pulley diameter on the alternator. It's been suggested I have a wiring issue, so I'm going to go over everything again - grounds, regulator harness, fused HD charge cable, etc...

The only other thought is a high output alternator. I don't necessarily need the higher output but it may give higher output at lower rpms? That way I can size the pulley to prevent over-revving the alternator at higher rpms.

The PA's have a lifetime warranty. Wouldn't they exchange it?

The high outputs only have 1 year...

They told me they would repair it and let me know the cost.

 

[ripped camel]

I just took off my alternator and it was NOT an OEM like I thought. It was a duralast.

Take it back to Auto Zone & get it replaced. That will get you by until you can get OEM.
