ok im having a dumb moment
ok my factory battery has special terminals on it due to having a fuse block mounted on top of it and regular terminals just will not work.
so my question is can i run my power off of the alt positive to a batt in the back of the car. and ground the batt in the back to the chassis. or do the two batts (factory and secondary) have to be connected as to not have ground loop issues. i know connecting them would add reserve capability, but i really dont want to have to get custom terminals made.
