2012 T190 starts and runs good. Three days ago I plowed snow for hours. Ran good. Today it started and engine ran good. I engaged the operator safety contraption and turned on the hydraulics. The bucket lifts and tilts but the tracks act like they do when you don't have the driver safety down. Mice or squirrels tore up my head liner a couple of years ago and made a mess of it. I never did more than stick it back up until it would stay and not fall down. I haven't looked into it yet. I'm not much of a mechanic (or much of an operator) but I'd like to have it ready for the next snow. What should I look for first? What can I test?
 
I would check for any thrown code, and then all your fuses,
if mice chewed on any wires they could cause a short, (or worse like a fire)
next I would be checking your safety switch, is it working?
is your hydraulic fluid up to needed level, some machine have safeties in them that stop functions on things if low! but it also should maybe throw a code or show an alarm icon on display
but if mice chewed wires that might not show things

Be sure to check that headliner.I was using my 763 one day when it suddenly shut down and wouldn't restart.I had limited knowledge of the machine at the time but tried everything I could think of to get it started,including buying many new parts, ignition switch, battery cables etc.
Turns out a mouse had gotten above the liner built a nest and chewed through the harness running through there.Very frustrating and expensive!

Thanks. My brother paid $3000 to get a bobcat totally rewired from mice over one winter. I'll get a buddy over once it gets above 50 degrees. We'll start there.

Thanks. I did check the fluids. I'll look for codes. I'm hoping to find some obvious bad wiring.
 
If your having mouse damage often, you might want to try doing some preventive treatments to deter or kill them !

adding moth balls,(I find they work well, minus the smell in cabs and such, the stronger the smell the better,
or start using actual mouse bait in easy places for them to find,in floor boards behind panels, in your roof panel for one!
rear access door and so on! you want any bait you use to be found where they like to go first

if your not into poisons for them, there are natural baits too, that will kill them without worries or harm to your normal pets9cats dogs and likes)

there are even baits that cause them to go sterile, they cost more, but they will help curb the population
also, if you can, its always a good idea to park your equipment away from things that attract mice in the first place

like any food source, be it hay, seeds, or ??

as the problem with mice is they love warm places when its cold out, so after plowing snow and parking your luring them to your machine
so the key again is to make your machine as least attractive to them as possible, along with the area around it!

as once they find a warm spot, they leave scent trails others follow leading to more and more using your machine as a warm home
and sadly for who know;'s why
they make the darn wire insulation out of materials that mice actually eat, this is why they chew on them

someone needs to make wire insulation that they don't like IMO!

Well, I put all my engineering and technical skills into motion. I took the headliner out and found no evidence of of any damage of any sort to the wires or anything. I don't have the strength to lift cab by myself anymore so I wasn't able to check anything in the engine compartment. So, I started it up and engaged the tracks and it took right off and worked great. Go figure. Thanks for all your help.
 
glad its working, but I doubt problem is resolved

odds are again you have a electrical connection issue, be it corrosion or just a loose plug or the likes
 
Are you sure the tracks werent froze in place. If not stored in a heated shop its a strong possibility. Otherwise you may look at the lap bar sensor.
