If you have the off-road acc. kit on you car did you keep the stock pully on your alt? I keep having charging issues with the pully that came with the kit!! Im really starting to get anoyed

 

iv heard not to put it on, or upgrade to a bigger alternator

 

Underdrive pullies will slow your alternator down. As a result your battery will not stay fully charged. Use atleast a 140amp alternator with underdrives.

Underdrive pullies free up some hp, but the accessories are now being spun slower, and reducing their efficiency. Namely the alternator and the waterpump.

 

id personally leave the alt. pully alone.
