Thx for your hard work!
38 bucks, sigh. I should have guessed the other isn't worth it. Well I will return to amazon. Both old and new fire tester but as we all know that ain't enough.

Not a problem, glad to help.

It does seem strange that both coils fire the tester but not the plug... But at this point given the testing you have conducted, especially disconnecting the kill wire, it's kind of hard to conjure up a solution other than a faulty coil. I would be surprised if a new OEM coil doesn't cure it.

Please do post up the results either way once you get your new coil installed.

Agreed, nothing worse than a bad replacement part to drive you crazy

I assume the new aftermarket coil came with a sparkplug wire already attached? Just want to make sure we aren't missing other possibilities like a bad wire or cap.

Yep,attached 3500ohm resistance to coil core.not sure what spec is.old one was 1500 and primary was in the Megaohm range-bad

Crap china coil

I called my local husky dealer who said that my current coil was covered under a lifetime guarantee. He ordered me a new one and it worked like a charm. I Will return the Chinese coil back to Amazon just based on principle

Glad to hear you got it straightened out buddy! The aftermarket coils are very hit and miss with these things, much like aftermarket CDI's for our trikes, especially those of chinese origin.

Oh and my 394 is even nastier than the vids I posted depict. I had a binding issue with the throttle lock spring and throttle trigger. The spring kept working its way out of its slot on the throttle trigger and causing me to not have the last full 1/4 throttle to WFO! After addressing this issue, the saw is on a whole other level of beast. We don't have any bigger wood to take a vid with that does a saw like this justice. But when we get into some more I will take a vid and post it up. I did noodle a chunk of ash to try it out after fixing the throttle lockout spring. 36" bar buried and it doesn't know the meaning of slow down till the discharge plugs up with those long noodle chips. Once that happens the chain carries the noodles all the way around the clutch and stuffs them back into the cut, and that's the only thing that will slow it down. Crosscutting, it's an absolute beast.
