New to me Stihl wood boss 024 AV not turning off.

[hsreliance]

I just got this saw and it fires right up but won't shut off. I check the black ground wire and it looks attached on both ends. the other wire looks pretty good too.
I have to choke it out to kill it currently so not using it (plus waiting on the new air filter). Is there some good photos or a good diagram that is easier than the manual?
I'll try and get some better photos. Maybe it was not put together correctly? I'm missing a part? thanks so much!

Looks correct. Use an ohm meter to test the continuity of the wires and metal spring. It could be the wire is broken inside the bullet crimp since it moves up and down and it's old. Follow the green wire and make certain it's screwed into magnesium. Pull lightly on the ends of the wires to make certain they don't pull out of the crimps.

You could just check to see if the green/yellow ground out wire is connected to a metal ground, I have serviced a few 026 and 024 saws where the wire was no longer grounded to the module.

Thank you both dsell and pioneerguy600! I will work on that later tonight.

My MS460 does the same thing . I have to take the kill switch apart and clean it . Doesn't ground out when engaged usually full of wood dust

Could be as simple as- with the master control switch up in the 0 or off position, the little brass coloured contact tube is not contacting the silver coloured spring, thus not completing the kill circuit.

took it all part and checked it with a continuity checker. For some reason the previous owner pinched the black wire on the edge of the carb. Replaced black Wire and now works fine. thanks for all the help! hope my air filter gets here soon

Got to like those easy fixes....

Where did all the flocking go from the air cleaner? Are those holes open to the intake? If so I wonder what the intake side of the piston looks like.

my guess is that is sat for some time and then when it was "cleaned" by the previous owner it got vacuumed off. I couldn't see any sign of it. Glad I was able to order a new filter (kinda hard to find).

Yes, the OEM filters and the rubber components for that series is expensive and hard to find. I see they have after market rubber isolators now. Keep an eye on the intake boot as old as it is.

Nice to find a serious problem.

Yes, sorry, the amazing part on those pictures, the piston and cylinder were in excellent condition. Every rubber part on the saw was bad. His Dad bought the saw for him new so he wanted it fixed. It was $200 by the time I got all the OEM parts and pieces shipped and then some labor. Those are not the most enjoyable saws work on especially that boot.

Yeah, whenever I find a ripped boot, there is usually some bad av mounts.
