Does killing "All" power mean it kills the engine and it will not crank either? I can't think of a way to do it with a single set of contacts like most switches that I've seen. I've never put a lot of thought into it either.



The easy way to do it is to put the switch on the negative side of the bat. But evidently the tech guys at NHRA aren't smart enough to allow that logical solution so they insist on the switch being on the positive side. Having the switch on the positive side causes several issues with the charging circuit but NHRA refuses to open their mind.
