Some times the safety switch is what causes the danger. On JD 4840 the neutral or parking brake safety switch is not the best connection between two small pins and the connector either does make good connection or the connector comes loose. Happens to be right below the small door on right side of cab. Can access the switch key through the door while wiggling the wire. Had to stop my employees from doing this. Point is the starter solenoid is good but someone has to stand in front of the tire to wiggle the wire while another person starts the tractor.
Replace the switch and/or the connector, whichever is causing the problem. I'm sure it won't cost that much, and won't take much time. But even if it were expensive, it's worth it to eliminate the danger of someone getting killed because someone took a shortcut.
We discovered a while back that there was a problem with one of the transmission switches on our 4440 when the HFWD engaged while the transmission was in neutral, and nearly ran over someone (who was troubleshooting something on the tractor). Fortunately there was someone in the cab who stood on the brakes quickly enough to prevent disaster. |
Know those pictograms of no starter jumping screwdriver?
