I looked around but could find a clear answer. I've rewired my 1971 Commando with a trispark and the sparx three phase system. I have put on a shorai battery and am in the process of replacing the ignition switch with a spst toggle switch to wire it. I have a tricon switch on the handlebar. How should I wire the kill wire on the tricon?

You should run the battery power to the tricon through an on-off relay and use the tri con switch to trigger the relay. This also works with the standard later kill switches where the ignition is fed through the circuit in the switch and often looses voltage to high resistance. The tricon switch earths the kill switch I seem to recall, so the relay should be normally on and by earthing the switch the relay will then switch to the other circuit and break the feed to the ignition.

To use a Tricon switch with an electronic ignition system you will need a single pull double throw (SPDT) relay in order to turn off the ignition system when the kill switch is depressed. I would recommend using the Micro automotive type relays. They are rather small and you can place them just about anywhere. I have supplied a couple of wiring diagrams to show you how to wire the relay/s into the system.
The first diagram shows an easy way to make your kill switch work. The relay is wired so that pins 30 and 87A are normally closed. When the kill switch is depressed the relay coil is energized and then opens the circuit.
The second diagram would be used if you plan on using a power relay to turn on your ignition system. When the ignition switch is turned on the ignition relay coil energizes by going through the relay coil and through the kill relay pins 87A and 30 and then to ground. When the kill switch is depressed the kill relay's coil is energized which opens that relay switch and then causes the ignition relay to turn off.
Pins 85 and 86 can be swapped. However, there are relays out there that have a diode shunted across the relay coil and those are polarity sensitive. Pin number 30 is considered common where power is normally connected however I drew these diagrams where power is fed to either 87 or 87A. The reason I did this is because the unused pins (87A or 87) do not have to be isolated from ground.
I hope this is of some help. If you have any questions please let me know.

Hi , I will put a kill switch to my Pazon Altair, and will follow that diagram, but one question, do I need a kill switch which act only when pressed on and then go back to its previous situation, or a permanent on/off switch, to work with that relay...?PeterJoe said:To use a Tricon switch with an electronic ignition system you will need a single pull double throw (SPDT) relay in order to turn off the ignition system when the kill switch is depressed.

The Tricon switch is a single pull, single throw momentary switch that is normally open. The switch goes directly to ground so that is why a relay is required. So if you are using a kill switch that goes directly to ground, those diagrams will be fine. If you are using a kill switch that has 2 wires going to it and none go to ground, you do not need a relay at all. You can hook the switch directly to the input of your Pazon system.

If your using a Pazon or Boyer electronic ignition system and you rewire the motorcycle for a negative ground system, you can connect the Tricon kill switch to the negative terminal of the spark coil at the same point where the black wire from the ignition module connects. I tested this on my Norton that is equipped with a Boyer Mark III and it works fine. While testing I repeatedly killed the engine with this method and it appears to have no ill effects to the ignition module. This is the only way I can think of without using a relay and using a kill switch that goes directly to ground.
Has anybody else tried this method of wiring a kill switch that goes directly to ground with other brands of electronic ignition systems? It would be interesting to know.

This might be a little off topic, but you can use the unused starter switch as a kill switch on Norton's that are equipped with Pazon or Boyer ignition systems. The motorcycle stills need to be positive ground (which most are). Simply connect the white and red wire from the 'starter' switch to the negative spark coil terminal at the same point where the black wire from the ignition module connects. I repeatedly tested this on my BSA 441 that has a Pazon ignition system. It works just fine. Just think, you can have two kill switches on the Norton and you don't have to think which button is the kill switch. Also you can omit the original kill switch that has corrosion problems. Of course you would have to test the other switch from time to time to ensure that it still works. But at least your engine wouldn't die unexpectedly due to corrosion in the original kill switch.

Hi peter, thanks for your input, I will buy a tricon and use your diagram, to kill my engine.........however I need a switch to fed the lights , as my wiring is for street/track days bike, just need some lights fore and aft , then a dinatek with spiral core HT leads, fed through a Pazon Altair , and a Shorai fed by a three phase alternator.........may be later on a MSD ignition, as soon as Jim Comstock will have them available.........quick connectors between the easily removable tail light and headlamp...et voilà!
Peter,
old post I know......
I have a Boyer MK 111 on my 71, with an unused push to connect switch on my Tricorn controls. The Bike is wired Positive earth. To provide an ignition cutout to my Boyer, would it be possible to connect one side of the push to connect switch to earth and the other side to the black wire from the Boyer on the Coils?
Would this act as a Kill switch as long as I keep the button depressed?
Would I this be OK for the Boyer, don't want to burn it out.
many thanks
Charles

For your kill switch to work as you described you need to rewire your bike for Negative ground. Otherwise you would damage your Boyer transistor box.
To rewire your bike to Negative ground is fairly straight forward. You need to change your Zener diode and rectifier to work with a negative ground system or 'buy' an aftermarket voltage regulator. Then you need to rewire your Boyer ignition system to work with a negative ground system. If you also have your blue 2MC capacitor you need to swap the terminals around as well. Then of course swap the battery terminals.
Last and least if you ever use your accessory plug make sure you know which one is plus and which is minus before using it.
I hope this is of some help. If you have any questions let me know.
