CX2510 No start situation (resolved)

[iptman]

CX2510 I've had for about 3 and a half years, 160 hours or so. It's done great for me up until yesterday. I used it this past weekend but went to start it, when I turn the key to <On> the dash lights up as it usually does, the tac sweeps and all looks right. When I turn the key to <start> I get nothing. Parking brake is on, brake lights lit up, clutch pushed in, in neutral and PTO disengaged. I'm getting 12.6v on the battery and the same on the starter post. I'm assuming it's one of the safety switches because there's no clicking or noises or anything. Is there a way to bypass the safety module just to narrow it down to a safety switch? I have the factory service manual and see where all the switches are so I can go down the list one by one but a couple will require removing panels. Any help would be appreciated.

I double checked the fuse for the safety controller and there's continuity. I had totally forgotten I had this fuse break on me a couple years ago and while I was searching for solutions to no start issues found my old thread from the way way back of 2 years ago. Anyway, when I twist the key back to light the glow plug I don't get the glow plug icon lit. Pic below when twisting the key back.

I swapped out the safety controller and I'm back in business. Apparently there's a TSB out there for this exact issue and dealers can replace it at no charge but my serial number didn't fall in the range. So I'm out $160 on the part and 15 minutes of effort. Pic of the old controller and bag of new part number.

Also, if anyone else runs in to this, before I fired up the tractor I twisted the key back to the glow plugs and the amber glow plug icon lit up on the dash. So if you're not getting that lit up this might help you zero it down to the safety controller.

Thanks for posting the resolution!

My CX2510 is a 2020 model and I had 2 of them safety boxes go out in the 1st year. Both replaced under warranty but still a pain. I haven't had a problem in 3 years and they said they updated that safety box to fix the issue on the 2020-2021's.

For anyone searching for a fix for this in the future.....

When mine crapped out it would not crank and you could not get the rear blade or bucket off the ground to load it on a trailer or move it. What I did was run a jumper wire from the switch to the solenoid to energize it when the switch is turned on. Unplug the small 1 wire plug on top of the solenoid and put the jumper wire on it. I then cranked it over 4-6 seconds at a time while holding the loader valve up and the blade set high.

It would not start but it would turn over and while the starter turned the engine, it turned the hydraulic pump and the blade and bucket would slowly lift. Then you can move the tractor in neutral if needed.
