Thanks for your imput, well today i brought my jd 240 out to switch some parts 1'st i switched the key switch, then the pto switch , then the ignition relay, then the pto relay. I even checked the transmission netural switch, iput a jumper wire in, still will not start no spark?? checked the fuses . they say nothing runs like a deer???? I,m lost don't know what to check next. maybe its time to give up and take it to the dealer ,it sure is flustrating. any ideas??????

PROCEDURE:
1. With the key on:
a. Measure DC voltage across top of battery posts.
b. Measure DC voltage between engine block (not
frame or battery) and positive terminal of both the
left and right coils.
c. If voltage is the same, go to step 2.
d. If voltage is more than 0.7 volts lower at the coils
than battery, check the following:
Battery terminal connection.
Battery to engine ground.
Positive side circuit from coil to battery.
2. With engine cranking, measure AC voltage across
pulsar leads (pulsar side of connector). Left pulsar
has pink with white/blue wires, right pulsar has
yellow with green/white wires.
a. Pulsars should each produce low levels of AC
voltage (as low as 0.05 VAC).
b. If no output, replace pulsars.
c. If output OK, go to step 3.
3. With engine cranking, use test light to check for
pulsation at negative terminal of both the left and
right coils.
a. Pulsation indicates ignition module and pulsars
are functioning properly. Problem is with ignition
coil, spark plug, or spark plug cap.
b. If no pulsation and pulsar output OK, check the
following:
Resistance at connector for coils negative lead and
pulsar connectors.
Ignition module ground (black/white) wire
connection to engine.
4. If battery voltage is at coil, pulsars are OK,
connections test good, and proper ground is
positively verified, replace ignition module.

Thanks ZDB for the imput. I followed the procedure you sent DCvoltage across the battery post was 12.83 . the DCvoltage between engine block and the positive terminal of both coils was 12.30. cranking the engine and checking the pulsers for ac voltage the voltage was 0.03 with cranking the engine and checking pulsation the light stayed lit, no pulsation on both sides , i also moved the ground for the ignition module to make sure its grounded good. So it sounds like it is the ignition module . would you agree?

I would agree your ignition module is suspect based on your troubleshooting.
I'll keep following this thread if you need any more info let me know.

WOW!!!!! boy prices on these modules is out of site .Called jegs and ordered one yesterday only $71.00 great price, but i got a call from them today and they are on backorder 90 days. If i wait that long i can sell my hay to the farmer next door. well I,LL search the puter some more.All i can say is some one is making some money on these puppys!!!!!!
Well i ordered it again because when i was on jegs the other day they said shipped with in 7 or 8 days , so i see the price went up but i figured well maybe it,s in stock again . But i got a call the next day mid aug. so we'll see. Are you having the same problem as i am??
I have a 425 aws with the kawasaki fd620d. I opened one end of the ignitor and sprayed contact cleaner in it and it started right up. I thought it was just one of the connectors but I cleaned them all but it still didn't have spark.

None of the Deere Dealers have the module in stock?
How about some other power equipment dealers whose products use the Kawisaki engines?
Good luck.
