Break Away Kill Switch.

[pullin]

I'm looking for the proper way to wire a break away switch on a model 126 for pulling.

[olds45512]

I would think wiring it into the positive wire running to the coil would be the most direct way.

There are 2 wires coming out of the break away switch. So your saying run 1 to the + side of coil. then would I ground the other wire?

No, take the wire off the plus side of the coil, connect that wire to one of the kill switch wires, connect the other kill sw wire to the pos side of coil. Your just passing current through the switch, if you fall off, the switch breaks current which stops the engine. You can do this at any convienent point along that wire, where coil positive leaves the ignition switch for example is probably closer to where your mounting the kill sw. My only question is what is the amperage rating if the kill switch? If the coil draws more current than the kill switch can handle, the sw could fail at an inopportune moment (mid pull), a relay may need to be added to prevent that.

Ok, I will have to look into that. It is just a break away used on a trailer.

I don't believe that will work then, the break away on a trailer doesn't supply power until you pull the pin.

Berwil can you please translate your abbreviation. Sorry sometimes it's hard to follow what someone is trying to say when you don't know what they meant by their abbreviations. Thank you

I think I fixed them all.




I agree with Tim about the trailer breakaway switch, I beleive those switches are normally open. I (we) thought you talking about something more like this.

tether switch

do you need to turn off a fuel pump? if not hook one wire to ground and the other to the negative side of the coil. that will ground the points to turn it off. if you have a fuel pump then you need a normally closed relay and a ground supplied when the switch is pulled that opens the relay. the 5 terminal Bosch relays work good for that.

You are correct but you will also cause the coil to heat up and prolly burn up if
forgotten and not disconnected with ign switch,and or the battery go dead.
Don't like that method, but it will work.
