Im currently at a loss. I wanted to upgrade to a 100 amp alt from the factory 65 amp and did that, but for some reason it wont hold a charge unless under a load. I put a volt meter up to it and it only reads 12.6v, bring up the rpms and it just creeps over 13. Are the 100 amp alt suppose to have a ground coming off the body or was i suppose to change to the voltage regulator to match output? Almost considering going back to a 65 amp. Any thoughts?
