Take a t-25 and take the two bolts out and look at wording behing switch maybe corodedcsnd need cleaned or loose possiblly. Accually next time you have that happen if external wire shake wire or bend allittle or if internal pull where they come out of bars. Look we're they bend sometimes you'll have a short there and that'll cause your issues you state.

 

I am 99% sure that is an aftermarket alarm system. Remove it and closely exam every place it attaches to your electrical system.

These older carbureted bikes are not cluttered up with electronics and computers. It is simple straight forward wiring.

I've almost never used the kill switch on any of my Harleys, like Dickey says. Others will espouse this same procedure because a number of members on this very forum had used the kill switch for shutdown, have neglected to turn off the ignition switch, and have come back to a dead motorcycle. This leads to angst, wailing, wringing of hands, gnashing of teeth, and yet another discussion on 'if my battery has gone completely dead, can I recharge it and use it again?'...

 

In 45 years of riding I have used the kill switch very few times on a bike that still had the rubber side down, always thought of it as an "emergency" kill switch.

Can't say I've ever seen a starter button "stuck on" when the ignition switch was turned on if it wasn't stuck on when the ignition was shut off.

Agree with others, sounds like it has something to do with the after market security.

 

I would suspect that something with the added on security system is causing the problem, and not the kill switch. Try to find out who made it, and which model it is, and search out what the problem could be. Or, as others have said simply use the ignition switch instead of the kills witch to shut off the bike.

 

Like others have already said turn the engine off using the ignition switch other wise you'll be back asking what battery to get cause you left the ignition on and used the run/stop switch.

 

Can it???

 

​​​​​​​...it could. ..

 

Like 2AMGUY, I'd suspect the alarm system. Maybe it's capable of disabling ignition and/or start?

I've always used the kill switch when I felt like it, and never had a problem. It's convenient to kill the engine, just before I coast into a garage.
