Husky 372xp bad coil??

I have a husky that I suspect a bad coil. It won't really start. It will pop and sometimes start. Sometimes not. Then just die never long enough to cut anything though like 5-20 seconds of running. If I squirt mix or out fuel in the carb it won't run either which leads me to think bits not a fuel delivery issue?

Like tonight , I started it. Was a hard start. I was warming it up and gave some throttle and it just died and would not restart.

I have swapped plugs and no difference.

I have a parts saw so I was going to pull the coil off to check it.

Is there a resistance check for a coil and what are symptoms of a bad one.

 

Swap the coil is an easy test.

 

Haha Yea I was going to do that! Just more curious for future things I guess to file in memory for a bad coil. Was late and I dont really convey what I mean well by text.


Coils can go bad in many ways I guess but I know on boats when they went and started getting wonkey they usually had a crack (havent looked at this one yet). But the craziness usually started when hot. Could happen anytime though. It was just like one day I used the saw next time I had trouble or could not start it. I have just set it aside for a few months as I have not had time.

 

I thought compression too. But it looks ok though the plug hole. And when not actually cranked yesterday sounded strong then went out like a light switch.

Yea with a parts saw I have a known good coil. That saw runs.

 

The problem with trying to ohm out the coils, is that they use solid state components in them to aid in generating the spark. The coil of wire itself may be good but one of the solid state devices could be going bad. The failure may not show up unless under high voltage also.

 

By all means swap the coil, because you have one. But I don't think it is a coil. Yes they can go at different times, display different problems... But your symptoms just don't sound quite right.

15-20 seconds isn't enough for the coil to get hot. Typically when they start going bad, they take a few minutes to get hot and start breaking down or cutting out.

I do think it is an electric issue, whether it be a grounded wire, switch, etc. When you swap coils, start tracing wires, look for bare spots where it rubs next to case.

 

Thats why I asked. When I use to boat more and work on those coil issues showed up more when hot.

 

Some saws are known to have ignition issues. I know my series of coil in my 064, it wasn't out of the ordinary to have a bad one. When mine started exhibiting those symptoms, I took the chance and bought another. Ended up being the problem too.

 

The coil is the only electrical on this thing. There is no kill switch hooked up. Not even sure if the wires are still there so...not really sure what else there is. I have it half taken a loose last night. Try and swap it tonight if I have Time.

 

I need to get time for the coil swap. Yea I dont know or remember if the wires are in there? Have to look.

I know choking is not optimal as it can flood the saw but this is a beater and was free so I am not too worried.

I do have a spark tester but its a cheap HF one and its hard to see if its sparking as its bouncing around as I pull on it. I guess I could do it at night and see it?

 

Was the coil. I had to unload the truck from firewood from the storms and messed with it and swapped it while I was out there.

The other day when I pulled it off you could see at one point the coil had crashed into the flywheel and bent some of the coil fins.

Also when I pulled the parts coil. I noticed it had two screws the one on the saw was missing the flywheel size screw. I swapped the coil and screw and saw literally started first pull and then kicked off choke and started and ran first pull no choke.

 

And since I was in there and saw the male connector on the coil I figured I would wire the kill switch back to working. So today I made a wire up with some connectors and put it back to working order.

Dex I now have a working kill switch on it

 

Alright Clem. Sounds like that saw is ready to be put to work.

 

It was put to work before the kill switch even was wired . I used it to cut the load friday.
