With all the pros who use this saw someone must have an idea for why I'm getting these weird "readings" of continuity when it appears there shouldn't be? Anybody?
Need help troubleshooting 200T-Kill switch not working

ok exactly what are you testing where

It is only one wire when the switch is on it grounds the coil I will help you again if you are there.

It's just like I explained yesterday. I've tested the switch. It works. There's continuity between the two springs/wires when the switch is in the "off" position. There's not continuity when the switch is not in the "off" position. So, I know that both springs are touching the rod in the switch mechanism when at the "off" position. I know there is continuity in the black wire from the spring all the way to the coil.
The anomoly is when I have it all hooked up, including the two front AV bolts. The forward AV bolt, when installed, brings continuity between both sides of the circuit (both green and black wires/springs) when the switch position is NOT even in the "off" position.
So, I don't understand why the saw even runs at all when the electrical system is basically grounding out? And, of course, the saw won't kill when put into the "off" position. I have to choke it off. I don't know what to test next. It doesn't make any sense to me.

Alright so I under stand is the circuit open or closed
1 take wire off coil put one test lead from ohm meter on it
2take ground wire off av bolt put one lead from ohm meter on it
3 open and close the kill switch and see if the circuit is opening and closing

3 open and close the kill switch and see if the circuit is opening and closing
Hey now wait and see what happens

I did this test already. I took the black wire off the coil. When the switch is in the "off" (closed circuit) position there is continuity between the wires (.2 ohms). There is no continuity when the switch is not in the "off" position (open circuit).
Im thinking that is how it should work bad ground at the av ? what continuity do you get if you touch the two probes togeter maybe your contacts are making a weak connection?

Sure. I get no resistance whatsoever when touching the two probes together.
I would like someone to test their 200t circuit to verify that there should be no continuity between the two sides of the circuit when the front AV bolt is installed and the switch is not in the "off" position.
0 when closed

Gotta run for now.

Do you mean 0 resistance or 0 continuity when closed?
closed circuit reads o yours reads .02 you have a loss somewhere check your wires separately there is a bad contact or wire nothing else it can be especially the ends

So I figured I'd put the handle back together and all the screws/bolts back in and just see what happens. Fired it up, flipped the switch to the "off" position, and off it went. Go figure. I'm suspecting the connection at the coil wasn't the greatest, but who knows. It seems to be working for now.
Now I get to fix the threads that the front AV mounting bolts go into. They're both stripped.

Tap it out a bit larger in american or metric whatever is a tiny bit larger

I think the stock bolts are 4mm x .7, and I'll get some 5mm x .8 that are hopefully the same length. If they're too long (from the dealer to retain the same head as the rest of the bolts) then I'll just trim them down and, of course, grind the circumference of the head of the bolts down to fit through those out holes.

just had a similar problem, pics of problem and repair coming!
