Re: NHRA Battery Rules
You can shut off the engine with the cut off switch by wiring the MSD trigger through it. I also run a 4 gauge alternator hot wire, back to the switch.

Re: NHRA Battery Rules
My Pet Peeve,
The N.H.R.A. doesn't allow relocating batteries to the trunk in Stock Eliminator but allows aftermarket blocks and heads, roller rockers, solid lifters, any duration camshafts, aluminum radiators, electric water pumps and fans, aftermarket oil pans, exotic transmissions, aftermarket disc brakes, wheelie bars, fuel cells, Kirkey seats, hood scoops on cars that didn't come with one, bogus combinations and Factory Super Cars that don't belong in Stock Eliminator. My Two Cents on a rainy Sunday morning in the Low Country. |

Re: NHRA Battery Rules
Lots of new cars have the batteries in the trunk. They last longer because the heat under the hood is hard on batteries.

Re: NHRA Battery Rules
Allowing a front mounted battery to be relocated in the trunk would be a common sense move.

Last year there were several fires caused by runaway Lithium batteries. The FAA even put a stop to shipments of Lithium batteries from a well know manufacturer due to lack and failures of compliance testing. |

Re: NHRA Battery Rules
I have a disconnect switch on the drive shaft hump next to me that kills all power and engine when when switched off. Its on the negative side of the battery. Just in case something bad happens.

Re: NHRA Battery Rules
It doesn't matter if you disconnect the Positive or Negative cable with the disconnect switch or where the switch is located...........
If you have 2 batteries (1 in the front of the car and 1 in the rear of the car), the cables still have to connect to the disconnect switch...... Even with the switch off, in the event of an accident, there would still be cables that run from the batteries to switch, that if damaged would create a short circuit............. If using a disconnect on the ground or negative side and the cable was damaged and/or crushed between the battery and the switch, the entire car would remain hot and not controllable by the disconnect, as in the fuel pump, fan, ignition would continue to be energized. If the hot or positive cable gets damaged and shorts between the battery and the switch you have a dead short and a potential fire The only safe way to wire 2 batteries, 1 in front and 1 in rear, is to use a continuous duty, high amp rated relay located at the front battery and controlled by the disconnect switch, which also controls the rear battery... Just my 2 cents, Bob Mulry PS: Not as safe as you thought it was...
