John Deere SB14 no spark

I have an old green John Deere SB14 that has no spark.
Kawasaki engine FB460V-RS01
It was probably manufactured in the 70s.

I'm guessing it would be either the coil or the trigger.
How can I test the trigger and the coil to see which one is at fault?
I can't buy the parts direct from Kawasaki, because it's a John Deere mower.
And of course John Deere wants a lot of $$$ for their parts.

The John Deere part number for the coil is AM116375 and the trigger is M131992.

After checking your part numbers.....the part is different. sorry


If you need to buy a new trigger get the replacement from Rotary it works and is about $20. Have a good one. Geo

I used to have test data to ohm the coil and igniter, but I'll have to do some digging to find it.

Test data on the coil and igniter would be very helpful.
That way, I would know which part is at fault.

I agree with geo on the rotary ignitor also. (part # 9334)

In my experience I have never changed a coil, it has always been the ignitor.

I understand how to check the coil.
But I'm a little confused on the trigger.


Am I supposed to reverse the polarity on the meter when checking from A to B, to take 2 different readings?

Thanks!

Thanks BFHFixit, that's the diagram I was hunting.

Yes, I think you reverse the polarity. I agree that normally the problem is the igniter, but every once in a while it's the coil.
