Kubota B2410 Don't start

Ricardo · Dec 25, 2007

I have a tractor Kubota B2410 and they have an electric problem the starter motor doesn't work.

I have checked all the fuses and they are ok, the batery is also ok, I have check the safety switches and they are fine, I think that the key switch is also ok.
So to start the engine I have to make a a direct connectin in the starter motor, in this way they start immediately.

Anyone could help me?
Could anyone send me the electric scheme of this model, to check where is the problem?

Check out your battery cables and the starter cables (especially the ground straps).
I'll wager you have a bad ground...

There's probably a relay in the circuit that takes the small amount of juice from the key switch to actuate an electro magnet that closes the circuit from the battery to the starter. Sounds as though it isn't working. Check through your wires from the switch to the starter more carefully. You'll probably find it. It'll have two big cables to and from it and a little wire from the switch (that goes to ground via the electro magnet). Could be it isn't there and is built into the starter itself. If so, it's okay if shorting directly to the starter works it.

There's usually some safety interlock's built into the starting circuit. Possibly seat switch or a switch built into the clutch pedal. You need to get a schematic for your tractor and follow the path from the key to the starter. Sounds like your cables are good, because you can jump it at the starter and it starts easily. Do you have a dealer close by to help you out with a electrical diagram?

sounds like safety switch has locked it out. schematic time or trace current with a meter or test light. You have power to the starter, first place to check would be starter switch, power in to it.

In addition to the things to check already posted, I would very carefully inspect all electrical wiring related to the starting circuit for loose conections, corrosion, pinched wires etc.
