Ignition Coil Question
I suspect my ignition coil is bad on my Deere Rider mower with a 9 HP Kawasaki.When the cold weather set in it just won't start anymore, no spark whatsoever then causes the engine to flood. Took the coil off and cleaned it and the flywheel, re-installed and set the gap but still no spark.
I did leave the grounding wire off thus eliminating any possibility of faulty wiring form the ignition starting circuit.
I will be buying a new one this weekend from a Deere dealer (51.00) but have a question I'd like answered.
Using a continuity tester I get continuity betwen the two legs and also from either leg to the grounding terminal.
I get no continutiy from any leg or ground terminal to the end of the plug wire. The plug wire is ok because on this model you can unscrew it from the coil and I get continuity from both ends. I tried baking the coil at 200 for 1 hour still no continuity.
A mechanic told me ther should not be any continuity between the legs and end of plug wire, that only occurs when the magnetic field is generated when the engine cranks.
I don't beieve that statement is true since the Kawaski service manual indicates there should be 10.9 - 16.3 Ohms by using the Rx1k range on the meter. These are the specs for the secondary coil from one of the legs to the end of the plug wire.
If anybody has a good coil laying around could you please test it and see if there is any continuity from anywhere on the coil to the spark plug lead. I will bring my meter with me when I buy the new one to test, but I would like to know in advance of what to expect.
