773 bobcat the hydraulic pressure switch gets hot enough to melt and leak it was a new switch only ran it about hour is it a faulty switch or do i have a wiring problem that is causing a short

SOURCE: running rough

get rid of this car sir, its a lemon. With everything you've changed the only thing left is checking parimeters on a scan tool for the senors. But you gotta know what your looking at.

SOURCE: oil pressure light on at idle for Volvo S40 MY2005 B5244S4 Engine

Since you are going to check the one way valve and cleaning the filter too, I would recommend to check the intake air filter and clean it throughly. After that use carb cleaner to free up the nozzles of the injector valve . If the engine sound better after using carb cleaner, add some into the fuel from the fuel filter or pump, whichever one has easy access, and gun your engine in short bursts, after which it should run better.........sodeep

SOURCE: I changed the hydraulic gear pump on my bobcat and had an AHC code light up. Before finishing my repair I started the machine and checked for hydraulic fluid leaks by letting it idle for a few minutes

Disconnect the battery for 30 minutes. On cars , this resets the computers. Back to factory specs. Worth a shot. If the sensor worked before, most likely it is good.

Testimonial: "I disconnected the battery and lifted the seat to clear anything that would cause the AHC code. The AHC is a safety feature that helps make sure there is weight in the sat before it will allow operation. If I understand correctly. your idea cleared the code but upon movement of the bobcat it reappeared"

SOURCE: I have a 90 763 bobcat when it gets cold I go to start it and the hydraulics won't kick out it stays engaged if I shut off the key for 5 times then it'll turn over and the hydraulics grab again butif

I would guess that there might be a bad control valve and the fluid is cold ...and leaking by the valve and engaging the drive train...good luck.

SOURCE: My 2002 TB a/c works for 20 min. Then does not. Checked , no leaks, clutch turns, condenser clicks until blowing hot air, replaced low pressure switch

Something to check because this has happened to me.....Make sure you have enough coolant in the radiator/overflow tank. IF the engine is running hot, the thermal switch on the AC compressor will turn it off to protect the compressor from overheating and damaging it. Don't go by the guage in the dash, it's usless. Hook up a scan tool and get the exact temp. Shouldn't be over 210 which is normal operating temp.
