Battery cut switch or not?

[jevs]

I am thinking a two pole switch will be fine with this car the more I look at it. The alternator charge wire can just be ran to the battery side of the switch. The exciter will be killed as soon as you switch the disconnect. This way there is no spike or issues to worry about unless the battery gets thrown from the car. In that case I doubt you will be too worried about it, and the wire that would have been discharged to the resistor will be detached as well anyway most likely.

 

The location is still tricky. "Can be reached from the outside of the car", could easily be the dash with a sticker on the outside of the roll cage next to it.
