I think my alternator is taking a crap. At red lights with the lights on the voltage drops and the lights dim. The battery is a brand new DieHard Gold. What is a good upgrade for the stock alternator? I have an decent stereo with an amp and I tow a camper that uses the truck to charge it's battery while in tow. I think I want the biggest(amp's wise) that I can get. What do you think? Thanks

 

Find a HD altenator. I think those are 130 amp and maybe an overdrive pulley would help too. I have a good stereo and my lights use to dim until I just put an overdrive pulley on my stock 105A altenator. Its a bandaid for now until I put e fans on it, then I will be purchasing a 200A one.

 

Well you can get new 130A take off for ~$95 shipped from ebay. It's a Delco one, and what I have on my truck also with the Optima yellow.

 

What's the name of the ebay vendor that sells them again?

 

I can't find them.

They are in Indiana from my memory and are like TruckandRVSupply or something... gimme some time and I'll research my credit card invoices to find them.

Allright peeps, the Hit Man has found the number for them...had to call up a few of my gals to dig through my files...

574-262-1850

Truck-N-RV Supply is the place. It was like $90+shipping UPS...

Enjoy!

 

For the 130? Did they have a 200?

 

Just new pull off 130s... they put out about 60A at idle w/ stock pulleys.

 

Not sure if that would be enough for my set up, with future plans in mind. I don't like the sound of the overdrive pulley on my 105, so I figured get the biggest available, until I started searching and they make a 250 for our trucks, although its almost 500 bucks!!
