View Full Version : 70 amp Delco alternator

Has anyone had one of these upgraded to 90-100 amp? Can this be done with original housing? I want to run 2 batteries and an isolator. I searched for alternator upgrades but didn't find much info. My dealer wants $750 for a larger alt and suggested aftermarket. Any info would be helpful.

Yes you can get it built larger. Call Ohio Generator @1-330-875-6677 Gus can get you a price. They close at 4:30pm central time so they just closed. But give him a call.

check your master circuit breaker...it probably will need changed.
