JD GT275 won\'t spark. Anybody have a schematic?

My JD 275 suddenly won't start. Put it in the garage two weeks ago, shut it off and today no spark.

It Will turn over. I jumpered the seat switch to be sure it is not that. And the interloc for the emergency brake is working because I can hear the solenoid for the mower click in and out.

I need a wiring diagram and some troubleshooting tips please.

How about the blade engage lever? there should be a switch on that too.

I think they had a part called an ignitor.... might be that....
although I think they usually start acting up with some intermittent problems before it totally quits.. it's a small metal looking flat squared piece on the side of the motor,, i just can't tell you how to test to verify for sure if that's whats bad..

good luck
