Installing kill switch !

[Dunnedriftin]

you should never put a kill switch on the positive circuit. always on the negative.

what happens if you crash with another car, metal to metal will you not get earth/negitive from there car or does it have to be from the one battery to compleat the circuit to have power if you get me??

Anybody that told me when i did mine was break the positive... :S

i know what your saying alright. i dont know which is right or which is wrong exactly. i just dont like the idea of having 8ft of un-fuze'd positive cable running through the car. in the event of a bad crash if it gets caught, or cut and earths you have a fire, or exploded battery. where if the negative gets cut or torn and hits the body it just earths anyway. if i was killing the posative terminal i would put a large fuse right at the battery.

know exactly where your coming from

what is the exact regulation on these switches ,is it to cut ignition (obdviously) but how ? battery ,ignition ,fuel pump ?

basicly cut the engine & power!

I would cut the ignition wire if i know which one of the 5 to cut, hence why i went for the battery in my car! Not a expert on electrics...

Take the plastic shroud from around the steering column off to expose the back of the ignition switch. With a multi meter check each wire (where it's soldered onto the ignition switch) with the key OUT of the ignition there should be 12v at one of the terminals… this is the constant live and has 12v sitting at it waiting at all times for you to turn the key and send the power on to all the other bits and bobs. This is the one to shut off the engine while using the motorsport 6 pole fia kill switch. If you have a turbo timer installed, brake into this wire before where the harness for the timer plugs in this will prevent the timer from holding the ignition on when your in the shit and need it off right NOW! You'll need to use the resistor provided too, to prevent the poles in the switch from arcing and over time destroying the switch. And then of coarse the the main batterie positive goes to the relevant side of the large poles on the switch. FIA spec to use the positive cable so that's what I did, makes sence seeing as you need to loop a live off the main electrical circuit side of the large poles to one of the small blade terminals on the switch. This side of the relay part of the switch is normally closed and this means when you shut off via the killswitch this part of the switch become an open circuit and it dumps residual power in the system through the resistor provided…
Right so ted rant over. I hope this was of some sort of help to someone.
