372 kill switch trouble

[brncreeper]

Search is down right now so I’ll post the question. Today my 372’s kill switch suddenly failed to stop the engine. I cycled the switch about a dozen times with no engine shutdown. The choke stops it for now until I can dig into it to find the problem.
Is this generally a problem with too much dielectric paste in the switch or a defective coil? The saw is still pretty new yet with about 5 tanks run through it so far.

I wouldn't worry about it;it's a Husky....they're born to run!

Here is a link for the workshop manual. Save a copy in case Husqvarna ever decides to restrict on line information as does Stihl.

Kill switch

Same thing just happened to my 372, turned out the fan had scrambled the wire leading to the kill switch. Replaced wire and works good now.

ahh..ive had this problem on the 395 a few times...it sure is a pain after you walk into the woods and then your saw won't start because the kill switch...we always just replaced the whole switch...i think they are around $4-5. although they prolly could be cleaned up or something..

I would assume that with only 5 tanks through the saw it is still under warranty. If that is correct, then clearly start with your Husky dealer at let them fix the problem.

husky

I know husky has a problem with the kill switches, my buddy has put 4 in his 281xp in it's ten year life. They go bad......just replace the switch.....bailey's has them. They are $4-5.:greenchainsaw:

EHP372=not stock

I have had the wires shake loose on mine a couple different times. I rewired the old switch with some new tiny spade connectors and I sealed it all up with some heat shrink. Has yet to fail me.

This is usually what I see!

Ya gotta keep a spare switch when you run a Husqvarna. Simple.

Two things could be wrong.Either the switch that you can check with an ohmeter or the lead to the switch is broken or was catched by the flywheel.

Found the problem. Apparently the ground wire came into contact with the FW, tore the wire to bits and flung it through the air injection. I pulled pieces of wire out of the air filter and fins. Nothing else got damaged, I’ll just make a new grounding wire.

On a new saw, I would check the wiring first. Something may have come loose. I don't know how your dealer is, but if they want to keep it for a week or more till they can get to it, you may want to fix it yourself if its not too much.

The plastic cable guide over the flywheel should probably have grommets or eyelets for the cables to go through instead of the integrated c-clips.

i had the exact same thing happen to me a couple weeks ago. only my wire caught the black air duct behind the fly wheel and smashed it up.
its the second time this has happed to me. those clips on the fly wheel guard suck.

Is this something that happens allot on 372:s ??

It happens only if your duct is broken or when you have to remove the starter and you dont take care to install the lead in those TOO thin guides.Clean the guide before inserting the lead.

 

[brncreeper]

Got it back together this morning, I heat shrinked both ends and used high visibility 14 gauge yellow wire so I could check on it occasionally with out taking the starter off.

I have never had it happen to me.....but have seen the results and bought a couple cheap saws that ran good for a 6 dollar wire.....lol
