Mike, they always test my cutoff switch at tech inspection at least here at Bandimere speedway, usually right after testing the neutral safety switch. That's how I found out it originally was not wired correctly because the motor kept running, albeit pretty rough.

Perhaps some tracks are less stringent than others....

Denny, I was considering installing a relay to cut off the alternator to battery connection so as to cut the load to the engine when racing, this can be significant load with electric water pump and fan etc. Are there some specific NHRA rules that would make this more complicated than a simple relay?
