Wiring fire, advice sought!

Tim, There is a little different way to wire it when using that set up. For what you are going to do I would back it down to a 50 if you could. Yes the system will pull up to that much. The wire feeding into the dash harness and fuse block (the red wire you are working with) is capable of handling a 55 amp current. If you used a lesser rated wire you may want to find something that can handle that. Most of the time you will not pull that much current because you are not running every thing and have a weak battery. So the alt. out put will not be that high. However the purpose of a fuse isn't to limit but to protect from a gross over load. The biggest thing to worry about would to find a wire that was rated a little higher. If you do that the fuse would still more than likely blow if there was a major short before it started cooking wiring.
