Run Stop switch not working

[Andrew82]

Would anyone happen to know why my run stop switch isn't working the only way for me to turn my bike off is with the key . I have opened the switch and everything inside looks fine . 1975 GL 1000

Broken inside it?
Did it always do this?
Has someone bypassed it?

[Andrew82]

Inside looks fine i opened it , i believe when my dad had the bike it did work .

Here's the basic schematic for the ignition.
Unless it's been modified..the black/brown is ignition switched power to the kill switch and black/white feeds the ignition.
You can prob

e the wires to see if it's true.
Has it been modified with electronic ignition?

[Andrew82]

I appreciate the help I don't anything has been changed it's all stock .

[virgilmobile]

Keep is posted.Let is know if you do or do not find the problem.

[Andrew82]

Can someone explain to me how does the run stop switch kill the motor ? I'm thinking it grounds the coils but not sure .

[virgilmobile]

It brakes the 12 volt power feeding the coils.Just like turning off a light switch.

[Andrew82]

Ok so if I understand this right the run stop switch gets it's power from the ignition switch (key) . I am thinking since mine isn't working my coils must be getting power directly from the key , i am going to do some testing this weekend and try to figure this out ,

[virgilmobile]

You got it.All the power goes to the kill switch and then to the coil/points.
The kill switch cuts power to the coils/points.

Ok so i opened the switch on the weekend and both the wires on the inside have no power to them until i turn on the key , when the key is on they both have 12 volts with the switch in the run position but when i put it in the off position they both still have 12 volts . I stumped

[Rambozo]

Unplug the switch and test out of circuit. If it functions, there must be a bypass somewhere in the wiring to the coils.

[virgilmobile]

Either the switch contacts/wires are shorted together.
Can you disconnect (remove)the switch then each wire again to see if it's wiring or bad switch?
