Checking for bad safety switch

Looking for a better way to check safety switches

When I check switches now I use a continuity tester and attach to coil kill wire,then I go to each switch and push it in with a clamp of some type or whatever I can find and see if I can get the light to go out.Does anyone have a better way to do this.

Why not activate the switch with the clutch, or PTO handle, or get on/off the seat? That way you don't have to try to clamp it.

Thanks,Cheese.Yeah I do some of that also.Then If the light stays on I know I have an issue with one of them.Do you go to each one and do continuity checks by each?

Usually not. I can usually cycle each switch slowly and see the ohm reading falter hard at some point while cycling the switch that is the culprit. If not, then I check to be sure each switch plunger is actually being depressed/released adequately. If I still can't see any sign of a problem, then I'll unplug one and see if there is still continuity or it goes away. When you get the right one, the continuity will go away. Then for kicks I might check the continuity across the switch. I almost always find the problem before getting to this point though.

Thanx, Cheese. I appreciate your explaining your procedures also.I'm checking continuity between the kill wire to the coil and engine ground and that may be wrong because that is a shared ground.I don't do many riders due to lack of space.I should be getting on to one side of the switch and kill wire correct?

From the kill wire to the frame. As long as the kill wire is unplugged, you won't have continuity when the switches are in the proper position and working.
