Check, clean, and tighten each and every ground connection. According to John Deere's manual, there can be no more than 0.1 ohm of resistance in the ground system. The manual has tests for it. If the manual you borrowed is the service manual, its quite thorough (and thick), and it can help you better than I can. I've worked on them before, and usually problems likes yours was because of a dirty, lose or corroded connection someplace, or more than one such connection. The battery ground is on the side of the motor block, down in the frame. A real bummer to get to, but its also a good place for oil dirt and crud to build up, and with the heating and cooling cycles from the engine, its possible the bolt has loosened up over time. Just follow the battery cable, and check all the ground wires as you go, as well as plugs and connectors.
