Duel batteries would be the way to do, I wish I had them. I have a 136amp alt right now and it does more then enough for me. A 205 from a CTD would be perfect for a duel battery setup, since the CTDs came with duel batteries anyways ha

 

I appreciate all the help and information. Thanks everyone!

 

I thought CTD's were singal battery 12 volt.. either way. a 205 running dual batteries would be easiest then adding an aux alt. but would take some work and a bunch of trial and error. would be a cool project tho .. if i end up going dual alts.. like 2 136's .. i would find two underdrive pullys for them since id be having to get a different length belt anyway.. i could run my house off my truck..

well not really.. but its a cool thought

 

HI i'm looking to buy a spare alternator as a precautionand was wondering if it has been confirmed that the grandcherokee alternator can bolt into a 2001 5.9 3500 i can take care of the wiring just hoping the mechanical is the same.

 

Hey,

Hate to dig this back up, but did anyone try the Jeep GC 150 Alt?

Shott, what did you eventually do?
