Hello and I Need Some Help with my John Deere!

Thanks for this site. I have John Deere L130. Up to a couple of weeks ago, it was running fine. I cut the grass, put it away, and a couple of days later tried to start it up again and nothing! The lights will come on, but it will not crank -it seems to me to be something electrical.

I tried jumping it with my truck and nothing. I cleaned off the cables to the battery -still nothing. I've tested all of the switches and relays as per the manual and still nothing. Over the past 2 weeks I have replaced the seat switch, the ignition switch, and the brake switch. I've even put a new starter on it, and nothing. NO CRANK! The fuse is fine. I can hear the PTO engage when I pull the switch, the same with the Reverse power switch (RIO?), therefore, I have not replaced them. All the wires appear to be intact. Nothing obvious, except it will not crank. It has worked great until it all of a sudden won't even attempt to start.

Any thoughts or suggestions?

Thanks

-Bill
