John Deere hydro 185 no spark

I have JD hydro 185 with no spark. It has a Kawasaki FC540V motor and I have disconnected the kill switch wire, flywheel key not sheared and when I crank it over with a spark tester or grounded spark plug with no spark. Is this an absolute test showing that the coil is bad? What other test can I da? Thanks[/b]
 
99% of the time its the ignitor module thats bad. Postage stamped size metal box on the side of the block with a white wire going to it from the coil. The only test for it is to replace it with a known good one.

You can check the coil for shorts or opens, but theres nothing you can do with the module except replace it.
 
You might want to take off the plastic housing over the fly wheel and see if mice haven't chewed on any of the wiring. Had one where they chewed of the coil wire to the plug.
 
I checked my Kawasaki motor and it has a igniter with the white wire coming into the igniter and then coming out and going to the coil (what I think is the kill wire). If the coil is good will it fire with the kill wire detached? What does the igniter module do?
 
Those little modules can drive you stark raving crazy!!! Every repair guy you talk to for small engines has a couple of good "spares" in the top drawer of his tool box. They have come down pretty far in price. Ebay is your friend. There are a couple of styles, just match up the pictures.
 
Found a little extra tip on these ignitor modules. This guy shows how you can
throw out the points and condenser all together. Neat!

Deere wanted over $60.00 for mine. Stopped at Carquest and matched a picture in their parts book.$15.00. Put it on and started right up. 5 years ago, BTW.
