Cub Cadet LT 1045

Hey everyone, I am working on a Cub Cadet model # 13RX11CH756, serial 1E107H10760. It has an electrical problem,,,won't crank. You can short across the solenoid and it will start. I have checked into it just a little bit, fuse is not blown, no power going to solenoid when key is turned to crank. I have checked ignition switch and one red wire is hot and with key on another red wire goes hot but nothing else. Does anyone on here have access to a wiring diagram, if so please send me a link. Electrical problems are not my strong suit. I have not check the PTO switch and the clutch/parking brake swicth yet. Thank You.

 

Do you have a wire that gets hot when you turn the key to start with the brake on?

 

I will check brake switch in the AM,,but nothing gets hot at the solenoid with brake on. One red wire on ignition switch is hot all the time and with key on the other red wire gets hot on the ignition switch. I hope to know more in the morning,,thanks Cheese.

 

Okay, but check for a wire at the back of the switch instead of at the solenoid. See if there is one that gets voltage when you try to start it at the connector on the back of the switch (beginning to trace the circuit back from the solenoid to the source of the lost connection). If none get hot when you hit the start position, then your keyswitch is the likely culprit. If one does get hot, but it doesn't make it down to the solenoid, then there is a wiring or safety switch problem. If the switch is working properly, you should have one wire that is hot all the time. One more that gets hot when you turn the key on (for the fuel solenoid), and one more that gets hot when the key is turned all the way to start. The source of power for this wire begins at the switch, then goes through the safety switches and finally to the solenoid.

 

Ok, thank you,,I'll check it out today and I'll get back to you. Thanks

 

Hello mowerdude,


If you find both the brake and safety side of the PTO switches test good and see no chaffed/loose wires in the harness, That stupid reversing module is likely your culprit. When bad they will cause a no start issue, If I remember the last I replaced was $65 range and comes with a new ignition switch.


Good Luck

 

Problem found and I thank ALL of you for your reply's and help. The problem ended up to be heavily corroded PTO switch with an internal short,,,would work sometimes and sometimes it would not work. The new switch is on Order. YEAAAAAAAAAAAAAAAAAAAAAAAAAAAA!!
