I have a new CX2510. Last night I turned it off at the end of daylight. This morning I went to start it up and it won't turn over. The dealer I bought it from has been below substandard in many areas, including the assembly of the machine. I don't even want to talk to them about this. There is another dealer a couple of hours away that I can go to, and they were pleasant on the phone when they were called about the problem, but their troubleshooting over the phone only could get so far. It is the weekend and I and I am really trying to get this figured out.

Here is the list of things that I have done to troubleshoot:

1) The dash lights up when turning the key on. I hear the relays click on.
2) I tested the seat switch and tested the clutch switch. They both work. I can sit on the seat and then stand up. I can hear both safety relays click. I have not tested the PTO nor the HST switch yet.
3) Of course I made sure the HST is in neutral, seat down, clutch pushed, PTO disengaged when trying to start.
4) I have traced some of the wiring looking for breaks but haven't found any so far.
5) All fuses are good

I am at a loss what I should be doing to test or continue looking at.

StudeHudson, before bridging two wires like you have, you need to check the circuit of the wiring, what looks to be a solenoid attached to the servo would have one wire being hot when the switch is turned on and the other would be an earth return to make the solenoid circuit, twitching together would give you a direct short and if your tractor is ECU controlled, be careful then.
You will need to trace out the start circuit, is there a safety sensor on the gear shift linkage, even the clutch pedal and also the PTO wiring, also need to read the start spade on the ignition switch with the key turned to start, the switch could be going faulty.

I am trying to find a complete wiring diagram for this tractor, have not found one at this time.
#3 is the solenoid. Anyway, I wired the unit back up as original. Jumped the starter solenoid with key on, and tractor started right up and runs. For now I have a temporary start switch wired up so that I can run the tractor and load it on trailer if necessary.
I will start chasing/checking the safety interlocks if I find a diagram.

Problem solved!!
I feel dumb but glad I found the issue. I purchased an on-line workshop manual and started going thru it. Came to the page discussing the PTO control knob mounted on the right fender. You have to push down and turn it to the "on position" for pto to become active. Push down and turn back and it pops up to the off position.
The bucket control arm/handle is mounted on the same side and when you pull the handle back and to the right, it actually touches the yellow pto control knob. I have never run the pto and I think while using the bucket/grapple control, the pto control got pushed into the "active" position when the bucket handle hit it. This is what the manual says-
The PTO switch is installed on the fender of the right
side from the seat. When the PTO main switch is OFF,
the PTO system is deactivated.
Also, when the ECU receives an ON signal from the PTO main switch, it
sends no signal to the start motor relay so cranking of
the start motor is not performed. (Safety measure)
A light bulb went off in my head when I read that so I went and checked, sure enough the switch was in active mode.
Turned to the "off" position and the tractor cranked up and started right away----

Don't feel bad about that at all.
A while after I got my Branson 8050 I had used the pto frequently while mowing with different mounted mowers.
Put it on a hay tedder one afternoon and tedded hay with went out the next morning and we couldn't get the pto to turn on.
Between the 3 of us standing there trying to get it working we had over 140 years of tractor experience,
It turns out on that tractor the lift arms have to be moved up a bit every time the tractor is started for the pto to work.
We had no clue and just happen to hit the external 3 point lift switch and all of a sudden the pto is working.
Read the manual that night cover to cover and no mention of that in it.

That is strange......They must have changed the joystick from 2021 to 2022......I have a 2021 CK3510 and mine does not come back far enough to even come close to touching the PTO knob.......

I wonder is that a cable operated joystick, if so the cables could be mis adjusted.

I don't think it is cable operated but it looks to me like it is installed wrong or something to have it in the wrong place...Like I said, mine in any position does not even come close to touching the PTO switch......

It looks like the fender mount for the switch is factory as I can see a welded on bracket holder.
The front loader control lever goes straight into a hydraulic manifold which has the hydraulic hoses attached.
No cables or levers.
I think at this point, I will see if I can put enough bend into the lever arm to have it clear the fender mounted switch.
