NO it does not have to be visible. They only need to know were to turn it off at. THE HANDLE MUST BE VISIBLE, not the switch itself. If you have a push/pull rod, PUSH MUST BE OFF.

2010 rulebook:

8:4 MASTER CUTOFF
Mandatory when battery is relocated, or as outlined in Class
Requirements. An electrical power cutoff switch (one only) must be
installed on the rearmost part of each vehicle and be easily
accessible from outside the car body. This cutoff switch must be
connected to the positive side of the electrical system and must
stop all electrical functions including magneto ignition. The off
position must be clearly indicated with the word “OFF.” If switch is
“push/pull” type, “push” must be the action for shutting off the
electrical system, “pull” to turn it on. Any rods or cables used to
activate the switch must be minimum 1/8-inch diameter. Plastic or
keyed switches prohibited. Switches and/or controls must be
located behind rear wheels on rear-engine dragsters.

 

Mine is mounted in the center of my tag with the word "off" written in sharpie. haha

Nobody ever notices it unless they know it is there.

 

old thread I know, but does anyone know if the battery still has to be mounted to the frame rails? and/or between them as well? - if so, that kills putting it in the spare tire area, and basically kills this mod for me.

 

Mines in the spare tire area...Ill post pics when I get it unloaded out of the trailer later today

 

thread revival...anyone have more pics of this?
