    LT133 will not crank over please help!!

    Hello, I have a 38" lawn tractor model LT133. I was cutting my grass and shut it down to empty the grass catcher bags. Upon trying to re-start to continue cutting, the mower did nothing. I checked the battery thinking it may have died but it is putting out +/- 13.0 volts. I could here an occasional click coming from the starter solenoid so thinking this was the culprit I replaced it with a new OEM solenoid. Still nothing. I am at a loss here. I checked the brake pedal switch, only to the point that it was firmly plugged in, also the same with the blade engagement switch.

    I used my jumper cables attached to my truck. The other end I attached to the NEG on the mower battery. I touched the POS cable to the POS on the starter with the key on and the mower fired right up. Runs great. shuts off with the key. All systems function as they should.

    Any and all help with this no crank issue is greatly appreciated.

    Thanks in advance, Bill

    Thanks for the schematic. I wonder if it could be the fusible link on the starter solenoid?

    I know that you said you checked the battery, but was that 13 volts under a load, or at rest? A battery can have full voltage at rest, but not hold up when under the load of starting the engine.

    I guess since I am not as knowledgeable as some, I think of the simpler things first.

    it's possible, that would be easy to test, just jumper across it. It can be anything in that circuit. You will just have to do some troubleshooting, eliminating one at a time to narrow it down.

    Let us know some finding if you get stuck and maybe we can give more insight on what to test next.

    Anyone else have any suggestions? I hate to have to take it to the dealer. It's has to be something simple I'm missing.

    Remove, clean, and reinstall the battery terminals. Then check for 12.7 volts again. If you can, check the voltage at the starter as someone cranks the engine.
