Pazon ignition

Hi Norton chaps I have fitted a Pazon ignition and have a kill switch that when depressed goes to earth ( not standard wiring) Where do I connect this in the cicuit ?

Thanks in advance for youre help

I have already checked previous posts and could not find any answers

I'm about to install my forst one in a Positive-ground setup, I'll have a look at the instructions and report back if nobody else has by then...

Think you will need to add a relay.

Relay or not, to kill electronic ignitions like Pazion one should cut the power flow not earth-ground shorting it out as if a lawn mower magneto.

Sorry for the short answer before but had to get movin' this morning. I was thinking that you could use a relay with a set of normally closed contacts in the power wire to the Pazon. The relay coil would be connected to 12V at one end and the grounding kill button on the other end. So when the button is pressed the relay contacts would open and break the power to the Pazon.

Yes don't ground the switching wire to the coils. I think the Pazon is same as the Boyer in that it doesn't switch the return side of the coil(s) to ground like points do. If you ground out the wire that does the switching it will likely kill the output transistor.

If it was me I would just use the right switch and avoid having the added complexity of a relay. I'm one of those that believes in having a kill switch in any case. I bought one of those single tri-color LED voltmeters and connected it to the power wire to my Boyer so I can tell right away if my power to the Boyer becomes flaky or low.

Pazon instructions do not indicate provision for a kill switch in the wiring diagrams for either positive OR negative.

So, I suppose you need to have a normally closed kill switch/button that opens the ignition input wire when pressed or switched.

Electronic ignitions should have two switches in line with the power feed, one the key switch and the other a kill switch, so if key turned off or kill pressed spark stops and no fly back voltage spikes into the black brain boxes. I hope no more of you ever learn the real need of a real kill switch that stays off at one touch, not hanging and hanging on to it while not exactly sitting upright pulling to a normal stop on a good slope.

The original kill switch on the Commando is part of the ignition feed circuit, pressing the button breaks the feed to the coils and stops the engine, however with age the points in the switch corrodes and with this high resistance will flow much less than 12 volts - this is critical with electronic ignition. Using a relay allows the full 12 volts to reach the coils/contol unit and the kill switch then becomes a simple connect/disconnect for an earth which is not voltage or amperage critical. I have found a relay with two feed terminals works well in this application rather than an on/off relay.

I have the diagram and noticed there was no provision for a' kill switch' I just wondered if the kill switch could of gone on the return side of the coil and if any one had done this .

The handle bar switch I have is an 'all in one' .Lights horn cut out etc .I might be able to rewire the switch to NC and make it the earth for the Pazon unit

I already have a remote on off switch fitted which sets the main relay for the ignition and supply but was wondering if a kill switch is fitted it would have to work for the mot

Thanks for youre replys

The PO who fitted my bike with a Pazon circumvented the kill switch (maybe this is what the manufacturer calls for?), routing straight from the ignition switch to the electronic unit (white line). I undid this by routing back through the kill switch after taking a close look at it and figuring that it looked like new and shouldn't cause problems. I just like having a kill switch.

Anyway, I've had no issues with it (or the Pazon) in the year or so since then. I can't remember exactly how I did this job since it was awhile ago, but I remember it being a simple task. Something about a white/blue wire... I did use the original wiring diagram and figured out which parts the Pazon had replaced.

I really like the Pazon/stock coils setup. Quite delightful.

I doubt it would be of any concern to an MOT tester.
