How can i test the ign. coil on a echo HC-1500 and also check the flywheel i have no spark and i have unplug the kill switch

disconnect any and all kill wires going to the coil... if you still have no spark then it can ONLY be the coil... if this produces spark then you have a kill system problem or your flywheel has no magnetism... and this can be the only solution as you do not have points/condenser or things just went full derp

Hi, have you tried a new sparkplug? Also did you set the coil to magnet airgap at 8 thou? Also when you say you by passed the kill switch did you do this by leaving the wire off the coil? Because if you did it at the switch end the wire from the coil may be chafed somewhere and earthing the coil. Hope this helps, regards Phil.

Check the kill switch terminals with a continuity tester (small multi-meter will work). If the switch is Ok and there is no spark, take off the engine cover and check the "air-gap" between the magnets in the flywheel and the ignition module legs.The closer the better, but you want about a ,008-.010"gap there...about the width of a standard sized business card. Metal feeler gauges "stick" of course to the magnet area in the flywheel and throw off clearance sensitivity. Try it with a business card. If not in range, then loosen the coil screws, double the card over, and let the magnets pull the coil legs into the card...retighten screws and check for spark.

if you have no spark

check for faulty plug 1st, then pull kill wire off at kill switch, then check for grounding ht lead ,
then pull kill wire off at armature , if still no spark most likley faulty ignition armature
i suspect the part number you need if its type 1 is 15662639130
replace it and set air gap and reassemble and test

here is web site for parts

or you could try www.partstree.com , go to echo saws , then find your model

The best test for an ignition coil is removing the wire(s) going to the kill switch at the coil. Most small engines will run with the kill circuit open & stop when you ground it. If you disconnect the kill wire & you have no spark, than it's a coil.. If you do have spark, check the switch & kill wire for a short

0.026 inch, or 6-8 mm is the plug gap.

The ignition coil air gap range is 0.012 - .016"" or .3 - .4 mm. This is the gap between the flywheel and the ignition coil.

An easy way to gap your coil is use a normal business card between the coil and flywheel, tighten the screws and remove the card.

take it to local small engine shop and get a free estament from them
they will tell you whats wrong with the unit
also have you tried to hold the coil wire and have a friend pull it over ??
if you get zapped then try replacing the spark plug

Well, if you have made sure that the kill switch wire isn't grounded somewhere, then it is probably the ignition module (coil). But before you buy a new coil, try sanding the side of the flywheel and the metal piece that faces the flywheel, (this is part of the coil).

Hello pbck98:

>>The Following is a Basic Instruction File I Made for Checking the Coil/Ign Coil/Magnetron/Armature on Small Engines. Any Input is Appreciated.
>>**To Check the Ign Coil; Remove the Spark Plug/s.
>>With a Good Plug, Wrap a Wire Around the Threads of the Plug and Attach the Other End of the Wire to the Engine Block. >>Remove the Blower Housing (metal engine cover). The Wire that is Connected to the Coil/Ign Module from the Shut Off Switch needs to be Removed (unplugged) from the Coil/Ign Module.
>>Now Check for Spark at the Plug.
>>If Spark, then the Shut Off Switch or the Wire is Bad.
>>If Still No Spark, then the Coil/Ign Module is Bad. If there are Safety Switches on this Unit and the Coil is Good; you Need to Check the Safety Switches for Being Bad and Check the Oil Guard Switch also.**
>>If you have a New Coil/Ign Coil and Still No Spark, then
>>Turn the Coil Over and Check for Spark. Ign Coils are Wound 1 Way for Clockwise Engine and the Oposite Way for Counter Clockwise Rotation Engines. I have Seen Ign Coil Boxed Wrong and Turning the Ign Coil Over will Correct the Problem.
>>The Coil is Gapped to .015in from the Flywheel.
For Better Assistance;
>>Send me the Make, Model and Type or Spec Numbers Off the Engine, Please. With these I can Locate the Proper Manual and Better Assist you.
Please, Do Not Hesitate, If I Missed Something or you Hit a Snag or this Does Not Correct the Problem, I am Here if You Require More Assistance.
Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Be Happy. Thanks.

Good Luck

There are only 4 parts to the 2-stroke Mantis ignition system: the spark plug, the "kill button", the flywheel with embedded magnets, and the coil with integral plug wire. There are no "points" to clean or refurbish. If you've tried a new spark plug, unplugged the wire leading up the handlebars, and the magnets on the side of the flywheel are strong enough to attract a screw driver blade, then it must be a bad coil. That's all it could be. End of story.

Cruising the internet I see where these Echo coils go bad all the time. You can order the coil, but if the machine hasn't run in several years the carb will also need cleaning. So one thing leads to another. The gear box grease also needs replacing each year. What I'm trying to tell you is these are disposable tillers and due to length of time, incomplete care/ storage, ....whatever, this one's time is up.

Sorry.
