Hey guys, I am new to the forums. Looking forward to being a member.
I recently purchased a 2010 Case 420ct series 3 with 1200 hours and have been running into issues. Problem is, I will be operating the machine, turn it off and it won't start back up again. Hydrostatic and oil pressure warnings are flashing and beeping, it also flashes 11 volts on hour readout.
At the start I figured it was a sensor and had to do with the angle of the machine. I would tow it level and it would start again, but I think that could have just been coincidence. I replaced the hydraulic filter and hydraulic pressure sensor to no avail.
I found that the 25 amp starter fuse was blowing, so I moved on to the starter relay as it wouldn't even crank a little with the key on ignition, but found that bridging the relay while the key is on does nothing. Right now I am stuck on the possibility of starter or battery, but the two flashing hydrostatic pressure and oil lights have me stumped.
Key points:
Problem occurs right after shut off and intermittently corrects itself.
Hydrostatic light flashing Oil Light flashing
11 Volt flashing on readout
No crank at all
Replaced hydraulic oil filter (no help)
New hydrostatic sensor (no help)
Starter fuse blowing occasionally
Bridging starter relay does nothing (no crank at all)
Any insight is appreciated

Case 420CT Series 3 won't start intermittently, even right after turned off.
