If you have a question I will attempt to answer.

If you wire the system as in the diagram, it will work as expected. Just do one wire at a time and follow the diagram.

The situation is this; you are using a toggle switch to turn on the master solenoid rather than turning it on by hand or cable.

At this time I have five cars in service with type system and all work as expect with no problems.

When charging the battery and if the car will set for a length of time during race day I recommend turning off one switch.


Larry, since Rusty above threw a brick at my head!!

Looking at your diagram, the On/Off Switches are on the positive side of the solenoid, which was my argument to Baker. When you shut off the solenoid it kills power to everything on the car "except" to the switches themselves. So, while trying to not be an ass, it does not meet the rules.
Under Batteries: Switch must be connected on positive side of electrical system and when deactivated shut off all functions in the vehicle.

So, again after Rusty bashed my head, all you need to do is make it ground the solenoid instead of applying power..

I do think the solenoid deal is a much neater install than cables/linkage.

If on the negative side for switched activation a shorted wire would keep the circuit live then right?

Why not use a double pole switch to cut power and ground?

Wouldn't change the point I was making.

as posted above, the switches could be wired to make the ground, thus, no power to the switches and I think doing so is an OK idea.

Or, the switch power wire could be fused.

Also as posted above, "I will be strapped in ----} The idea is that the rear switch is always on. The drivers switch controls the system. In the case of an emergency, the rear switch can be turned off by anyone within reach of it.

Thanks Larry. That’s slightly less than 1 amp to energize continuously.

Do you know what switch they are using in the back?

Been doing it Larry like describes for years. I use a aftermarket push/pull switch that looks like a farm tractor headlight switch. Doesn't need to be more then a 10-amp switch, it is just dropping aa ground on the solenoid and it kills the solenoid and power to everything.

We ended up using one of these switches on my brothers dragster, and it works fantastic! Now, with the question of the an alternator, how would you wire that up? Would you use a second switch so that you have a battery cable going from the battery side of main cutoff to one side of the alternator switch, and then the second going to the alternator? On my mechanical switch in my car, I had to swap in a 4-post moroso cutoff so that when the power is killed, there was no voltage going to the alternator from the battery, and the alternator circuit was also off of the electronics side of the switch that way the car would shut off when pushed. Also, would these Cole Hersee switches handle a 16V alternator with 100 amp output?

How is it wired to the electric solenoid?

I have the alternator and charging lugs on fused wire going to main on one side of solenoid. On other side the big hot wire goes to starter and one goes to rest of components ign, switch panel etc. That way if switch is off all power is shut off and car dies immediately.

So is the wire to the alt. always hot?

Yes, it basically goes to battery, both tie in on the solenoid.

@ sides of the solenoid. 1 side goes to the battery pos and the other side generally feeds everything in the car including the starter. So you're saying that the alt. is piggybacked on the battery side of the solenoid and remians hot no matter what?

Yes, because if you put it on starter and ignition side when you turn off power ignition and everything would still be hot as long as alternator is running. Must kill all power when switch is off. Your battery is hot all the time.
