Hello, I have a John Deere 6810, built 2000 and the next few days problem.In not turned by electrical engine. if I go directly to the electric engine starts,but do not go on before and back.I doubled the wiring between electrical engine and ignition switch.Now the engine starts go 5 meters before and 5 meters back and stops.Manifestation occurs after each start.What could be the problem?
