Default emergency off switch/toggle

I have a 1972 ironhead, points ignition. The key/ignition is set low and to the rear on the left. It is hard to reach and sometimes it is hard to find neutral on the bike. Thus, when I have the clutch pulled it is near impossible to get to the key. I was thinking for safety I should mount some kind of emergency off switch somewhere easier to get to. I was thinking that I could simply interrupt the power from the positive terminal of the battery, maybe using a toggle switch mounted somewhere easy to get to. Would this work? And is there a certain rating/type of toggle switch that would be best to use.
Thanks,
Ben

If you interrupt the line between the IGN circuit breaker and the ignition coil you can use it at night and not lose the lights. This is what the stock wiring does. Gray wire from the cb to the run switch, white from the switch to the coil.

Thanks for the quick respose IronMick. The bike is not stock, it is one of the 70's custom diggers and nothing seems to match the service manual. I don't ride this bike at night due to multiple safety issues (no turn signals, horn, mirrors, speedo, etc). Getting to the battery is easier than to the ignition and coil, that is why I was thinking of interrupting at that level. Any toggle switch recommendations?

you should just put a thumb operated kill switch on one of the handle bars. thats your safest bet, if your worried about saftey issues. im sure there are many different options available.

Welcome to the XLForum.

Locate it near the throttle and use it every time you turn your scoot off so it becomes second nature so in an emergency you'll use it without having to think about it.

A switch at the battery would require a high amp rated battery cut-off switch and NOT as simple as a SP/ST Radio Shack toggle.

However, you can easily use a 'regular' SP/ST toggle between the key and the coil as the amp load is easily managable. A 120v/20a SP/ST toggle from Lowes/Home Depot will be fine. Just have to find a place and that will be awkward and ugly I believe.

For your -72 though, Bob F has shown you what you REALLY need pictured above!


EDIT: Actually, any automotive 12v toggle off the board of a chain parts house will obviously work too. However, you will need it to be waterproof. Accordingly, If you gotta have a toggle, check with your local boat shop and get a waterproof panel switch.

Here is another novel idea. Why not just relocate your key switch back to the original -72 position between the cylinders under the tank on the left? You get a key you can safely reach, a choke cable mount and can even add the horn back if safety is really a concern.

Thanks everyone for all the help. Mr Bentwrench, how high an amp rated battery cut off switch would I need. I am trying to keep the bike looking as close to how it was built as possible and I don't want to relocated the key switch. Also, the battery drains when the bike is off and I was hoping a battery cut off switch would also solve this problem. Thanks again,
Ben

Ditto on the rating of a switch to open the positive on the battery. Most would wire up a relay and open the relay with this amount of amps being switched.

Toggle is easy. Just splice it in the hotwire to the ignition switch and make a custom cool panel to mount where the ignition was stock under the tank.

Maybe there is a slight misunderstanding here.
There is no amperage involved with what you want to do.
The only place you are going to experience any measurable amperage is on an electric starter....... and thus the reason those two cables are .....well, cables...... not 16ga light wire.

So what you want to do is select what kind of switch you want to use and decide where you want to mount it.
I recommend you use a toggle switch, rather than a push button.
If you use a toggle switch you will find the wire running between the 'I' terminal on the ignition switch and going to the coil.
Cut this wire and run one end to the toggle switch.
Off the other terminal of the toggle run a wire back to the coil. You are set.
To start the bike you will have to make sure both the switch key is 'on' and the toggle is 'set to on'

If you were to use a push button switch you would do the same wiring set up except insert a push button in place of a toggle switch.
The problem with this is most push button switches are made to be 'open' and you have to push them to close the switch.
Well, your ignition needs electricity all the time so a push button is not going to work unless you can find a 'reverse push button' that opens when depressed rather than closing when depressed.

You will still have to have the key turned on to start the bike of course.
A modern Harley has a key switch and an ignition toggle switch as well mounted on the front brake lever.

If you happen to turn this switch off unknowingly, the next time you try to start the engine the electric starter spins the engine over but no start is the result. You wonder what happened until you realize what you did.
Then your face gets a bit redder!
Been there-done that with my 2003 Dyna.
