I have a 2000 Suburban and am going to be running all the power wires from the battery to the back end this weekend and want to get everyones opinion on where to run them. I was wanting to know if anyone has worked on a suburban and if you have do you have any suggestions. I was planning on running them under the vehicle and bringing them up from the bottom. Is this a bad idea, or a good one. I have something that the wires will be run in so they won't be just out in the open. I am just running 1/0 power wire and think this would be the easiest way to run the wires. Any ideas would be greatly appreciated and if anyone has any pics of how you did the cables up near the battery they would be greatly appreciated. TIA

For 1/0 wire you should run the wire under the vehicle. Just make sure that you use a grommet and secure the wire under the vehicle securely. I shouldn't have to say this but I will anyways, make sure it is fused. You can bring the wire into the vehicle underneath the wheel well shroud.

Of course would be fused, and I am adding a HO ALternator and wonder why the factory power wire to the alternator is never fused. When I change to the HO should I also fuse that lead to be safe or is it not needed since it is so short and is what charges the battery?
Also when I fuse up front and run to the back it is going to my second battery with an isolator. How should I fuse at the back? Should I also have a fuse after the isolator and before the battery, and a fuse between the battery and my distribution? I have been reading the rule books and they aren't all that clear to me on this. I know up front I need a fuse at least 18 inches or closer, so do I want to do the same at that back battery?
Thanks for the first reply as well

I will ask again and see if anyone knows. Does anyone know the rules regarding a second battery on fusing. Do I need to fuse it just like the front battery with 18 inches of each lead coming off it? I read all through USAC's rules and it isn't real clear so any help would be appreciated. And if anyone knows a way to get ahold of IASCA's rule book in an updated copy without joining I would appreciate it.

Just hook up your isolator as directed. Then run the wire to the new battery in the back with a fuse after the isolator. You only need to run the power back, you don't need to run a ground. Just run a ground wire to a good peice of metal to the second battery, shorter the better. Depending on what your going to be using on the second battery I would run a wire to a distro block with a fuse in line and then a fuse in line with evrey output. If its going to be lights and radio, as in a cop truck, a fuse block from someone would be the best bet.
