quick kill switch question!

I would like to run a simple kill switch to the coil on a TJ. My question is how long can I make the wire going to the switch and then back to the coil before I get any issues with the timing? Or maybe a better way to state it: I know electricity travels fast (or electrons if you want to be technical) but could I add 5 ft. the length of the wire going to the coil and not have any problems? Thanks for the time- Tim

Re: quick kill switch question!

Are the light bulbs in your house that are further away from the circuit breaker dimmer than those that are closer?

The answer is no because that relatively short distance is so minor it makes very very little difference. So adding 5 feet of wire won't be a problem. There will be slightly more resistance in the wire because it is longer, but in this case it doesn't matter.

Re: quick kill switch question!

Even easier than the coil for a kill switch is to run an interupt to the input of the ballast resistor on the firewall. The vehicle will run for a second or two, then die. Nice way to make thieves think that it is a piece of crap not worth stealing... [img]images/graemlins/cool.gif[/img]

Re: quick kill switch question!

Your best bet is to enable and disable the Anti-ShutDown (ASD) relay. This kills the fuel pump and ignition system in one fell swoop! No fuel to the engine and no spark. It's makes it kinda hard to go anywhere...

Re: quick kill switch question!

You don't need to run back to the coil, just to ground. Add a wire to the POINTS side of the coil, and run it into the cab to a set of ignition points. Make sure that the points are grounded.

Then take a little square of innertube and tie a stout string to it. Stick the innertube patch into the points, and tie the string to some part of your body.

If you get out you'll pull the patch from the points and that will ground the ignition, just as if the points in the distributor weren't opening. Also a reasonable anti-theft device. And cheap.

I ran from the coil to the dash back to the coil cause i was in a hurry and didn't want to figure it out.


If.. someone were to try and steal my Jeep, it would crank over all day long day in, day out... but never spark.

Re: quick kill switch question!

Dex, you can install a emergancy kill switch pretty easily. Buy a purposely designed kill switch (like one from Flaming River or Speedway Racing). Get one with 4 terminal posts on it. Wire the larger posts to the hot side of the battery, the smaller posts to the output of the alternator. A turn of this switch efectively shuts down the vehicle.

Re: quick kill switch question!

I don't understand that. Could you sketch out a schematic? Do you know what the connections are through the switch you describe?
