Small Engines (Lawn Mowers, etc.): 345 john deer starts in aux

Question
My 345 john Deere tries to start in auxiliary.  Checked all wiring everything seems to be connected correctly.  Could it be the circuit board?

Answer
It could be the circuit board.  Have you checked all the safety switches to make sure they are properly working?

Picture of the wire diagram.

Do you have a multimeter to check the switches and circuits?
