AgentTyler Posted June 29, 2012 Report Share Posted June 29, 2012 Is it possible to skip the isolator and run a power wire straight from my alt to my battery in the back and keep the power wire that goes to my front battery too? Just curious because I don't have awhole lot of room under my hood for an isolator.

AgentTyler Posted June 29, 2012 Author Report Share Posted June 29, 2012 I always thought they helped with regulating voltage? I guess I really don't know, thats kinda why I was asking. I just know that running Wet Cell with AGM in parallel is not good.

AgentTyler Posted June 29, 2012 Author Report Share Posted June 29, 2012 Well basically what I would do is run a power wire straight to my front battery from my alt, and then a power wire straight to the back battery from the alt and not even connect the front battery with the back. It would act in the same way as an isolator, kinda.
