Kill Switch. Thread starter Twin Pots Start date Feb 7, I wish to fit a handlebar mounted kill switch on my 67 Bonneville. It is a positive earth machine as it should be and I run the standard points.

I understand the kill switch should work by grounding the coils or just one coil? I would like to confirm the wiring connections needed before I stuff something up, fry my coils etc.

On every forum with advice on kill switches everyone asking has a Boyer or similar electronic ignition fitted so not terribly helpful. Is there anyone out there who can confirm which side of the coil points side?

If I join the wiring from both coils together, which would happen if I run them to the kill switch, surely this will cause a non running type problem but will wiring just one coil to the kill switch still stop the engine? Any help gratefully received. I still have the original on my ' So, basically, just a single-wire grounding button, hundreds of different ones availablewired with one wire to each coil.

It works fine apart from one problem, the switch kills everything apart from the left side ignition with the engine continuing to run on the left cylinder only.

Not quite what I had in mind. I dismissed the issue of also killing the lights as a problem as I am highly unlikely to ever ride at night and far more likely to drain my battery when parked up by leaving the lights on. Question one: why does one cylinder keep firing and Question 2 : could I simply run run all wires coming from the ON side of the key ignition via the kill switch first so that both switches have to be ON to power up.

I could just kill the ignition as described by Grandpaul previously by grounding the coils but I like the added benefit of killing the lights as well.

He claims that a "knowledgeable friend" as well as the dealer salesman recommended he leave the run switch alone The logic being if that switch were to ever go bad, one would spend hours trying to diagnose the no-start condition looking elsewhere.

I'm not sold on this, but whenever I take his extra bike out for "exercise" I follow the owners rules. Ive never considered such a practice with the many bikes metric I've had in the past, nor with my current Can anyone of the more experienced and knowledgeable forum contributors weigh in here?

I'm not one of those real "knowledgeable dudes on this subject, but anyone who has any common sense and reads their manual would know that it states you should always use the on-off switch to shut off the engine. How could a salesman or even a wrench-er from a dealership say anything different? I guess opinion over-rules what the factory manual states I always used the kill switch instead of the ignition key switch to shut the engine off. I have only ever seen the kill switch go bad on 30 something year old bikes.

Mostly cause they were never cycled and froze in the run position. To each his own, I guess. I use the kill switch to shut off the engine every time.

Going to work one day in 20 degree temps, with my heavy gloves, I accidentally killed it while pulling into the parking lot. Just about wore my leg out trying to kick start it later during the day until a co-worker came out, flipped the kill switch back to run and it started right away.

Since then, I've had the pleasure once of returning the favor for a "stranded" friend. I've heard the same thing from a Victory dealer. His logic was that the key switch does the same thing and has to be cycled, so toggling the redundant kill switch only wears it out.

Now I don't give a damn I can fix it if it did wear out.As you know, there are various ways on how to turn ON and OFF your motorcycle, be it via the ignition, kill switch and side stand, but what is the proper way? The Ignition switch feeds electric to the kill switch on its way to the fuel pump relay and engine control relays. It is a series of connection. The ECU powered up the same way regardless of the switch kill or ignition.

The kill switch is really just an engine turn off switch, not a full power shut off switch. Obviously this will drain your battery. That said, the kill switch only affects the fuel pump and engine control. When the throttle is jammed at high speed and there is no time to take the hand off the handlebars to turn the ignition off. Just use the kill switch and the engine will be off and the motorcycle can be slowed down. Some said, the frequent use of the kill switch can also cause the switch to stick and fail in the OFF position due to wear and tear of the contacts within but how often does this happens?

The ECU recognises the grounded coils and cuts power to the fuel pump and injectors. Use of the kill switch instead of the key switch will shorten the life of your coils. The lock position on the key switch is to extend the steering locking pin after turning the handlebars to the far left.

Thanks again.View Full Version : Ironhead leaving key on, coil damage- fact or myth? A quick internet search finds a lot of assumptions, but the consensus is not there.

I believe with points thats a true statement. IF the points are closed you have current flow and will overheat the coil. Leaving the ignition in the ON position overnight will totally fry a stock or an Accell yellow coil. I didn't learn the 1st time. Yes, if points are closed, for a prolonged period. No damage resulted, just a flat battery. Seems like I was lucky. I'll throw this out there: Take a piece of 16ga wire and connect it directly to the positive side of your battery.

Now flick the other end of the wire against your frame or any ground that's away from the battery. You can do this all day long and that wire ain't gonna get hot. NOW, clamp that wire to your frame. Ahhh, point well made rivethog and point well taken.

Too much consistent current flow is not good for the insulation which thereby cause failure of the component at hand. You make some good points, but there is a significant difference between an AC holding coil and a DC ignition coil To quote Steelworker Intro by Steelworker: An ignition coil is a pulse-type transformer, consisting of a primary low voltage winding and a secondary high voltage winding, wrapped around a laminated iron core.

The primary circuit is completed by points or ignition module closing the primary circuit to ground. The flow of current induces a strong magnetic field in the laminated iron core. When points or module open the primary circuit, the strong magnetic field in the core collapses suddenly, which induces a high voltage electrical discharge in the secondary circuit, producing a spark to bridge the electrode gap of each spark plug.

The ignition coil is intended to pulse. A typical ignition capacitor is. With sloppy tolerances, I've seen points transfer contact material in either direction, depending on whether the capacitance tolerance is high or low. Without a capacitor, points will not only transfer material rapidly, but your comment about introducing voltage back into the coil is critical. Don't try to make any RPM without a capacitor.I have a Kawasaki Ninja Zx-6r. I have heard from many people who do and don't use the kill switch.

Some people say it is good for the bike for it is part of the process of turning it on and off.

But I have also heard the using the kill switch continuously with turning it off and on that it hurts your bike. I have heard the it varies depending on the make and model of bike.

I want to do the process that is best for my bike, so do I use the kill switch when turning my motorcycle on and off or do I leave it in the on position and just use the ignition key? And what are the negative affect of turning the motorcycle off the improper way? Using the Engine Cut-off Switch will not harm your bike in any way -- that's what the switch is for! That red switch is Federally-mandated to be in the same spot in each motorcycle sold in the U.

The "proper shutdown procedure" we teach in the Basic Rider Course is turning the motor off with the cut-off switch, turning the key off, and turning the fuel petcock to "off" if your bike has one ; often referred to as "Thumb, Key, Valve".

While you certainly can use the sidestand switch to shut the engine off the switch shuts off the motor if the sidestand is down and the bike is in gear - lets it run if the bike is in Neutral not every bike has this and if you change bikes -- even just to ride a buddy's bike around the block -- you could put the stand down while the bike is in gear and running. But I have also heard the using the kill switch continuously with turning it off and on that it It's a legal requirement.

In the past most bikes had the ignition key on the side of the headlight or elsewhere along the side, just not in the now-familiar position in the middle of the dash. In fact some still do my '04 Triumph Thruxton has it on the left side of the headlight. Anyway, if you have a mishap and the bike falls on the side where the ignition key is located it might be impossible to safely turn the engine off without a kill switch.

So you can quickly shut down the engine in an emergency.

Tip over switches are a recent development. As mentioned above, different makers put the ignition in different places. It's easier to push the switch located next to your thumb than it is to reach for some switches. Back when I took the MSF course a couple years ago they had us use it as part of the proper shutdown procedure. They didn't say if it harmed the bike one way or another. Personally on my bike there is a kickstand switch so if you put the kickstand down while in gear it does the same thing as the kill switch.

This is how I shut mine down since I don't back into my garage. Whether you use it or not does not harm the bike. Whoever told you it harms the bike is an idiot. The only harm that could be done is if you leave the key on and the battery goes dead.

The kill switch is there so you have a way of shutting your bike if the key breaks or if you are in a crash and can't reach the ignition switch but can reach the kill switch, etc. Using the kill switch is how I turn my bike off. Have been doing it that way since I've owned it and it hasn't hurt it at all. I was told to use kill switch is a good habit so in case of emergency you don't automatically look for your key.

does not turning the kill switch off drain the battery?

Hi guys! Ive heard some guys turn the key off each time because otherwise your battery will drain as to the kill switch.

BUT I figured killswitch off is just as good? I ask this because my batt seemed a bit low so I charged it up the other night. So does leaving the key on and kill switch off still kill the battery??
