Case 1840 Skidsteer Won't start

WiJay · Aug 19, 2022

I needed to move some hay rd bales today and I jumped in the 1840 and it turned over but would not start, it seems every few years I have to replace the solenoid stop switch, so I always have a spare I replaced it and nothing happened. It has fuel, it ran perfect last time I ran it (3 weeks ago) I noticed that when I turn the key to do a system check when done it will buzz that the check is completed and I can start it and it didn't make the buzzing sound, not sure if that is connected to the problem or not.
Any suggestions for trouble shooting?
Thanks Jay

What injector pump have you got, there were two rotary and one inline used, hold the solenoid with your finger tips and have a second person turn the key on and off, you should feel the solenoid jump if it's good, if that checks out open an injector line and crank the engine over with the throttle on full and see if it's injecting fuel, have a look that the air intake is not blocked etc.

I am still having issues with the 1840, I got it going in August but after sitting the winter now it is acting up, I installed a new ignition switch in fall.
We checked out the solenoid and not getting power to it, power out of the ignition so it is somewhere between, (wiring, fuse, relay?) Difficult to trace the wires Any suggestions. Thanks for the help.

Do you mean the starter solenoid or the stop switch, the starter circuit will have a neutral start switch, the stop switch could have a relay, look in the parts book, you can use a temporary jump wire to power the solenoid to get going.

Yes, the solenoid stop switch. sorry i wasn't clear about that.
I was wondering if there was a relay that could be faulty? Trying to follow the wires are almost impossible.

Note the color of the wire going on to the stop and look at the wires going on to the igniton switch to see they it is the same, if you find a wire the same test it at that point to see if there is power coming off the switch, how many wires are going to the pump stop, I asked you in your first post what pump you have as there are three different types, some have more wires than others.
