HELP! ms362c no spark 2009 model

[rustypete]

ms362c 2009 model no spark bought a new coil from my stihl agent part No.11404001302 £138 no spark yet nothing removed spark plug earth it to cylinder and turned it over with my drill on the fly wheel very fast no spark nothing toke off kill wire nothing could it be the fly wheel magnets seem to be quite strong toke off the two wires and tested them thy are fine any help will be much welcomed thanks rustypete

Did you use the spark plug and plug wire from the original coil?

Does all the wiring to the fuel solenoid look good?

it is not a mtronic

it is not a mtronic just fly wheel and coil

no new coil come complete with coil cable and plug boot getting reading from coil with multimeter

Does flywheel show any signs of damage? If it took a hit from something, the magnets could have changed polarity and you won’t get spark.

It’s pretty darn rare, but it happened to me once. The flywheel and coil contacted each other in a saw I bought. There were obvious scrape marks on the flywheel. Both magnets remained “Strong”, but it wouldn’t create a spark. It drove me nuts.

Did you try a new spark plug? Far more likely the plug failed than the coil....

Are you sure you are spinning it the correct way?

@rustypete, when you used your mulitmeter, were you metering just the coil itself? Did you try and ground one lead, put the other in the spark plug cap and the pulling it over to see if you are getting any deflection on the multimeter? I had a saw the other day I was putting back together and gapped the coil with a business card and didn't get any spark, but the multimeter showed deflection when pulling. I narrowed the gap on the coil and then finally got spark. Saved me from playing swaptronics with spark plugs when they were not the problem.
