Husqvarna 55 ignition coil

Hello the wire from coil to stop switch is grounded and the chainsaw will not start, is the coil bad and in need of replacement

Posted by on

  • Hillman314 May 11, 2010

    How do you know its grounded? I measured the (dc) resuistance of my 55's coil the other day, and measured a couple of ohms. (after subtracting the resistance of my tester's probe wires. What I think I really measued was the low (DC) resistance THROUGH the coil. I found your post while searching for what the proper (DC) resistance should measure. A low (DC) reading is what one would expect through a "coil" .

    well you could check the coil resistance with a multimeter.

First thing you need to do is check the wire for any bare spots or if it is melted to some thing inside the saw.if neither is present then the coil will be bad.call husqvarna,the coil should have a lifetime warranty on it.hope this helps,let me know

I need a wiring diagram, mainly from ignition switch to coil/stator.


pull the black ground wire off from the coil,try to start the motor,if it starts,put the wire back to shut it off,,,one or all of your safety switches is bad,you can bypass all the safety switches(as long as you dont care),by putting a switch connected to the coil and the other side,a ground,if you want safety switches then you have 3 to choose from to replace,2 stop the mower from starting and the 3rd stops it from running if it did start,here is a 42 inch,pretty much the same,you didnt tell me what model or make, http://www.ereplacementparts.com/craftsman-917279841-riding-mower-parts-c-158286_174089_460323.html

How do I adjust the air gap on aignition coil on a husqvarna 240 chainsaw


Use an air gap tool. Clean the area where the coil mounts on the engine with emory cloth to make sure you get a good ground. install the coil and lightly tighten screws (just over finger tight) slide in the air gap tool and align the coil, make sure both legs of the coil are even on the tool. Snug the screws and recheck the gap.

Stihl MMS171 won't start. Can't see any spark on the plug when trying to start it.


hi
first you need to replace the spark plug
if that not works you need to look for any damage to the wire that go from the spark plug to the coil and the wire that go from the coil to the stop switch ( this wires must not touch the metal case of the chainsaw )
if all good looks like you need to replace the coil
sorry for my bad english hope you understand

It's about Husqvarna 345 chainsaw. I would like to know the resistance value between spark plug wire and blue wire from ignition coil, and between spark plug wire and the ground and finally resistance...


The easiest way to test is on the machine. Remove the ignition switch wire from the module coil. Check the pole gaps of the module by inserting a thin business card into the gaps after turning the flywheel magnets under the module. Loosen the module mounting screws to allow the module to contact the magnets, tighten the screws, and turn the flywheel slightly to release the card. Turn the flywheel one full turn to make sure the gaps don't close up further. Use a fresh spark plug gapped at 0.020" and try for spark. If nothing, replace the module. This gets around measuring resistances while trying to evaluate the module. Hope this helps!

My cs-3450 saw has no spark. the ign wire shows to be grounded. bought a new coil, still no fire. the ign wire on this coil also shows to be grounded. what is the problem?


disconnect the on /off switch that is how it gets grounded so that it will shut off may be a bad switch disconnecting it will allow it to start.

No spark


if you have tried new plug, remove pull start cover and remove kill wire from ignition coil ( tape wire up so it wont get caught on flywheel ) and refit starer cover - try and start if it starts - faulty ground wire between coil and stop switch or faulty stop switch

but if it does not start or saprk faulty ignition coil indicated
obtain a newignition coil and fit up and set air gap to 0.010 " and tighten the mount screws and refit the stop switch wires and starter cover and let rip

With the ign. sw in the on position should i have voltage on yellow wire ging to coil


The ignition switch on a chainsaw operates on a ground. When the switch is "on" the coil is not grounded out, and the magneto can supply power to the coil. When it is "off" the coil is grounded, and no power gets to the coil. If you are checking for spark you can bypass the switch by removing the wire to the coil. It may just be a bad switch. A two stroke motor uses magnets to power the coil through the magneto. If the switch is grounding out there may be no spark!

This chainsaw hasn't been started for several years. I pulled the spark plug and it isn't getting any spark. This mdoel has an on off switch.


First check for a disconnected wire at the switch. If that checks out ok,follow the wire from the switch to the ignition module(also called the coil). Most saws use the on/off switch to complete a circuit to ground to kill the engine. If the wire to the ignition module is missing the insulation and grounding to the body that will keep the saw from providing spark.

If all the wires and the switch proves ok you may have a bad module.
