[QUOTE="audioatg, post: 7200041, member: 570057"] Thought I read some thing down the road that Heat is not good for charging. Like to much heat. I know they get hot. But an overly heated alt will do less. Also from what I have learned in the pass. All gauges of wire in the system should be the same size. Even more so the Amp wires. Doesnt matter how long but needs to be the same size. So you cant have a o gauge for power wire and a 4 gauge for ground wire. Next thing. The battery in the back. Do you have a ground run from the front battery to the back battery. If not and the Back battery is grounded to the chassis. Check and see what the resistance reading is on the ground. Take you ohm meter. One lead on the front battery ground and the other lead on that chassis ground you have in the back for the back battery. See how much the resistance is. If its really high you need a better ground. Next thing is your amp. What do you have it grounded to. The back battery or a ground point on the chassis. I would do a ground point on the chassis not to the back battery. [/QUOTE]
