Battery cut off switch

Okay, the "am I missing something" question that I had has been answered by 67dart273 and crackedback. However here is what I know about NHRA. They do not care about the power being hot up front. What they are concerned with is that when the switch is shut off everything stops. The engine, the fuel pump, fan motors, everything. The simple way does make that happen. Now I will concide that if there is power still to the front at the alternator that it could be an issue for an electrical fire. But I've spoke with 3 different NHRA saftey inspectors and the "simple" way as described in these threads meets the NHRA requirements. But I do agree that the relay system as described by 67dart273 and crackedback would be better safety wise and for street driven vehicles. Thank you guys for the clarification.
