Master Kill Switch Wiring? - 08/30/10 03:12 AM
My Master Kill is currently on the negative side so it won't kill the car if you just turn it off while running. I obviously need to correct this to pass tech. I did a search and Plan to rewire like this...please let me know if this is the way to go with a 1 wire alternator.
On your mater cut off switch, you have 2 posts.
Post 1 - Battery positive wire (assuming your battery is in the trunk so it should be a short wire) and the wire from your one-wire alternator (This should be the only wire from your alternator back to the battery side of your master switch).
Post 2 - the main power cable that supplies power to your car (switch panel, starter, ignition, etc)
This will allow the power to be cut off to the car by flipping the master cut off switch from on to off. NHRA/IHRA Tech will check that at many tracks, they will have you start the car and then they will flip the switch and if your car doesn't die they will fail you.
If you also have charging posts on your car, you would also run the positive cable from Post 1 on your master cut off switch to the red post and then run a wire from the negative battery post to the black post. That would be 3 wires to that post.
This will allow you to charge your battery even when the master disconnect switch is in the off position.
