Re: battery cut off switch

Any switch you install should have at least the same current-carrying capacity as your primary battery cables. The "green knob" jobs barely have enough contact area for a 12-volt car and no where near enough for 6-volt. The best of all still remains (IMO) the Cole-Hersee rotary switch which is more than ample even for 6-volt systems with long runs of cable where the battery can be below the rear seat.

Installation should always be on the grounded cable. For batteries under the front seat or rear seat, an inside installation is very simple and convenient but I can appreciate the problem with underhood batteries; I open my hood of the Carib at least twice for each car use and that gets very old quite quickly. I've yet to find a good convenient location for these. I have seen cases where folks break the hot cable and mount the switch on the cowl with the handle inside above the gas pedal - still not very convenient and dangerous as well. Seems we still need a good idea for this.
