    Didn't intend to have a Deere fleet - it just happened 310C, F915 & 5200

    Had a battery that tested good with volt meter. Eventually found a broken terminal on battery that prevented full amps. Try a jumper cable from battery terminal to starter terminal. If it cranks then the wiring from battery to starter is bad.

    Thank you bigbull. I will have him check it. What is an easy way to check alternator in the field?

    Can always be something we didn't think of... Try jumping the starter solenoid, first. Make sure the tractor is out of gear... This will test the starter and cables. If it cranks, then the control circuit is at fault.

    Alternator won't keep it from starting. Bad alternator would cause battery not to charge therefore a no start condition. To the OP...to check the alternator get the tractor running and look for 14 to 14.5 volts at the positive alternator terminal or at the positive battery terminal.

    If you can get me a link to a diagram or scan and e-mail to Ron@opfa.com I can give you some more specific recommendations.

    Do you get a click or anything from the starter or the fuel solenoid?

    As far as jumping the starter solenoid, there is usually a relay that switches current to the solenoid (which is a bigger relay) if you can trip that small relay which will take a small current, that might be safer. Alternatively you might be able to pull the relay and jumper to the line feeding the starter solenoid.

    If the start logic / delay model is damaged that could account for not starting. so could a damaged starter relay.
    Seat down switch ?
    PTO engaged?

    Good luck
