Battery in Trunk Wiring That Exceeds NHRA Requirements

I wouldn't wire a car in that fashion, that's how I would deal with it. :)

Whether it's a one wire or a fielded alternator, this is how I do it. The field wires will be killed by the cut off switch at the speed of light via the system power wire/ignitions switch being dead.

I know I posted a pic of my battery tray set up in one of these threads. With my set up, if the CD relay locks closed (on), you are no worse off than if you had a direct live wire from battery to alternator. However, the cutoff switch will KILL the car/engine. The charge wire is isolated from the other side of the cut off switch.
