Battery in Trunk wiring completed, now no power at all

I guess you are not wiring this to go to the track then, but just for personal use?

Because in this drawing,there is about 15 ft of welding cable going to the front of the car which is live at all times.A short anywhere along it's length could be a major problem.
The alternator output does not need to come all the way to the trunk.You can stick it on the starter or the big stud on the Mopar relay or on the "s" terminal, or anywhere in that circuit that is convenient, if the Ammeter is not being used.
Unless I guess if the Ford solenoid is also in the trunk. I didn't think of that.
If the Ford solenoid is in the trunk, then you crackedback are right, the drawing is good as is. And then, to Mr.Bel, sorry to have thrown you a curve there.
But if the Ford solenoid is in the trunk then you have at least one 10 or 8ga wire going from the alternator all the way to the trunk, which is live at all times.And you have another 8ga wire going from the Mopar relay to the trunk, that is live whenever the disconnect is passing juice. So you still have not solved the 15 ft live wire issue, only moved it to two smaller wires.
My reading of the rules back in 2004,said that when the safety guy trips the disconnect all juice stops at the switch.Has that changed?
