Hello all,
I am new to the forum and also new to Mahindra tractors but I am a mechanic by trade and have worked on several Kubota, J/D, Massey tractors over time. My problem is with the 2014 Mahindra 3616 Shuttle that I have. When I go to start it, it seems like there might be a dead spot in the starter motor but the local dealership said a new starter is up near $1000.00 and they've never seen one go bad. What happens is that it will intermittently click sometimes and I need to keep bumping the key to get it to finally start. At first I took the neutral safety switch (mounted on forward/reverse handle) completely out of the system and it seemed to work fine with the wires directly connected bypassing the switch. I bought a switch and replaced it... same problem. I have cleaned/checked the battery and terminals, checked/cleaned all my connections at the ignition switch, neutral safety switch, starter, etc. I have removed the starter and bench tested it and it tests perfect on the bench. Also if I disconnect the signal wire from the starter mounted solenoid and hook in a remote starter switch to the battery it works fine every time. I have checked voltage at the signal wire when the no crank/clicking occurs and I'm getting slightly below battery voltage and I am also getting voltage through the solenoid to the starter motor itself....
What has me stumped is that it works fine with a jumper wire or a remote starter button in place of the factory starter signal wire but when the signal is coming from the key through the neutral safety switch sometimes it wont turn over it just clicks (and its definitely the starter solenoid clicking throwing the bendix, I can feel it). Does anyone have a wiring diagram for this particular tractor or something close? If the thing didn't work with the jumper or remote button I would say it has a dead spot in the windings and replace the starter but seeing how the starter is $700 or whatever they said and the starter works fine with the remote button/jumper I'm thinking there's some kind of gremlin in the wiring or there's a relay/switch or something else that I don't know about. The only thing I can think of at this point is rewiring the whole starter signal circuit myself with a new ignition switch but I don't know what else is in that circuit. Any help or diagrams would be greatly appreciated..
Thanks guys
