no spark

[christoff]

hello, i have a lawnboy model 10671 with no spark, are there any known problems with the coil etc thanks chris

Not unusual for the coil to go bad, simple repair job.

thanks, i tried to measure the resistance according to specs but im not that handy with a meter, it says 2.5 ohms on a 20k scale i believe the amount should be 2,500 to 5,000 ohms to be the correct amount is this amount that im showing say that the coil is ok?

 

[Rivets]

How did you take that measurement? From what to what?

 

[christoff]

the instructions say from the positive lead of the spark plug and the negative lead to the engine ground should be from 2500 to 5000 and i am getting 2.5 on the 20 k scale

That reading tells me that the coil is shorted. You'll need to replace it.

 

[christoff]

ok ill replace it, does the 10671 model have points or a modual , and if it is points do they go often? or the modual for that matter? :smile:

 

[Rivets]

CDI module. Yes they do go out. I replace about a dozen every season.

 

[christoff]

how can i check this unit?

The only check you can do is disconnect the ground (kill) wire, take the spark plug out, attach it to the spark plug wire and hold it to ground. Now carefully spin the flywheel as fast as you can by hand. Careful not to pinch your fingers. If you get no spark, bad coil. The tester for coils costs a lot more than I will spend, very few places even have one.
