my current alternator seems to be going week
and im interseted in buying a high out put alt because i have a large sound system that draws a whole bunch of power and i already have a optima battery so i thinking about a high out put because my current alt isnt making 14v anymore its only reading 12 now on the dash

my question is what does the stock alt push out in amps at idle and at peak. im lokking into buying this alt off of ebay what do u guys think about it

I would verify output via something other than your dash gauge.

They are typically very inaccurate.

I would get either a Durango or V8 GC alt. Both are close to drop ins, and both are higher output.

 

well nornally its been at 14v but lately its been getting weeker and weeker

 

Again, I wouldnt trust the gauge.

For all you know a ground for that gauge is getting dirty and not working correctly.

 

well like i said i have been blasting a big sound system and i think that its finally taking a tole on my alt
and your right u cant always trust what the gauge reads but i trust mine because its always been right

 

so what do u think about ordering a high out put alt

 

Factory wiring sucks too. Bigger alt with no wire upgrade = wasted effort.

 

ill upgrade the wiring to the battery

 

Do u think that this alt will hold up

 

Stock is somewhere around 80 amps. How much juice does your system pull?

 

I'm not sure but I have an 1800 Watt amp an two 12s and I draws a couple volts from the dash gauge

 

A true 1800 watt amp would draw 138 amps at 13 volts. Assuming that is the amp's true power ability (most fudge the ratings way up by using some variation of instantaneous peak power instead of continuous), you'll have to upgrade the alternator and all associated wiring.

The dash voltmeter- they always read right until they don't. Check with a DMM and see what you have.

 

What Do u think about the alt on eBay I posted

 

I don't know anything about it other than what the seller has in his ad. Have never purchased one.
