One wire alternator

I have a one wire 60 amp alternator on my 75 Duster, and my battery is also in the trunk. I added a 60 amp fuse at the battery for the alternator, just incase of a short in the charging circuit. I used a #6 high temperature wire between alternator and the fuse in the trunk. I also added a Ford style starter solenoid to open the hot wire at the battery when the ignition is off, or the kill switch was opened. The solenoid I used could be replaced with a two pole kill switch as stated above. I was able to redo all wires from the engine bay and hide them for a clean look. I agree that all power needs to be off or contained within the battery if you open the kill switch.
OK, so what you guys are saying is that if the wire, or any wire connecting the battery in the trunk to the engine bay still has voltage when the disconnect is off/open, It is dangerous and does not meet NHRA rules. I'm a little bit confused as to why there is a need for a relay in the circuit. If one was to go with the Cole Hersey four pole disconnect and when it is open/off the main battery cable and the charging wire are disconnected from the engine bay, would this not be effective and meet the rule? I was going to fuse the charging wire at both the battery and the alternator also for safety. As far as the one wire alternator, no noe has had problems from what I see. I wonder if any companies offer a kit to convert a Chrysler alternator myself. I have lots of them kicking around my garage. Thnks alot guys, I appreciate your help.
