after spending 1000 for what they said was a full rebuild, the tractor will not start. The solenoid will not even click, but I can cross over the trigger terminal and it will turn over. PTO works, lights, work. I am thinking it must be a ground or a safety switch. A wiring diagram or a service manual would help. Just cant afford to take it back to the shop since the estimate was only 300, then they tell me they either have to fix it ot get it back in pieces.
