JD STX38 Wiring Diagram

Report to Moderator

Does anyone have a wiring diagram for a John Deere STX38 with the yellow deck. My mower starts and runs but when I flip the switch to engage the blades they do not engage, so I"m trying to trace down the wiring and see if I can find the problem.
Thanks, Jim

and on the engine:
Koehler 12.5 HP

Jim, without all the serial number digits I'm doing a bit of guessing, but I believe this the right one, please compare the wire colors to be sure

OK, thank you very much, I should be able to trace things down fairly easily with this, I"m sure this saved me several hours of "now where did the yellow one go again" etc. I"ll let you know how it turns out. Thanks again, JimBee

Take a test light to the switch, see if the electricity comes out the other post when the switch is flipped. I'll bet that the electric pto clutch is bad.
