I bought my first skid steer about a month ago, it is an L565 with about 3700 hours. When I bought it, it had a bad oil leak by the oil cooler, the light was flashing red that shows a gear with a teardrop in the middle of it and arrows to either side of the gear. The guy at the dealer said the system was not making enough pressure and this was the reason the light was flashing. I fixed the leak and it still does the same thing. It flashes that same light along with orange "stop" light, for about 30 seconds then shuts off. It will run on service but the bucket has no tilt. Before starting the skid steer as it is doing the count down you can hear a clicking in the back coming from, I am assuming a solenoid under the main engine fuse panel. It clicks 2 times. If anyone has any ideas it would be appreciated.
L565 shuts off after 30 seconds.

The low pressure the dealer was talking about will be low engine oil pressure or low charge pressure. It could be as simple as a bad sender or as bad as a worn engine (if its engine oil) or a problem with your charge pump (if fitted with a dedicated charge pump).
Sorry i can't be more specific as i don't own one.
It shuts down because of a safety system. Its designed this way as to help prevent damage to the system when it detects a problem

I saw in some other treads that there is a sensor with 2 wires coming out of it under the Hydro. Oil Filter for the charge pressure. I took them wires and connected them. Now when I turn on the key the Light does not flash on the EIC. I have the radiator out for repair right now so I have not started the engine to see if I can run the skid steer for longer than 30 seconds without it shutting off. How do you check these sensors to see if they are OK. I have a multimeter and could check it for resistance if someone has the numbers for it. Thanks to any and all that reply.
You would need to know what the sender is set to and install a pressure gauge to ensure you are getting that pressure in your charge circuit. Charge pressure is generally 110 PSI but some systems use 200, it all depends on the design of the system.
I am not real familiar with this electronic stuff. When you say sender do you mean the thing I am calling the sensor? I could take out the sensor or sender and adapt a hydraulic pressure gauge into the system at that point pretty easy if that would be ok. Is the charge pressure at this point either 110 or 200 PSI? If I had AUX. Hydraulics I am assuming the pressure would be higher at them outlets. Correct? Thanks,Paul

Yes, what you call a sensor is also known as a sender. If you pull it out and install a manual gauge you should get 100-200PSI depending on the systems charge pressure setting. You are correct with the aux couplers, you should get about 2,500-3000 PSI there.
Thanks Tazza, I will check the pressure tomarrow night and report back with what I find. Paul
I was also wondering what RPM the pressure should be checked at? Or does this have an affect on pressure at this point in the system?
It will change slightly, but from idle to full throttle, it should be pretty much the same. The only thing that will change is your flow rate, but you aren't measuring that at the moment.
I checked the pressure last night and it checked out at 115-120 pounds. I found out on messicks that there is a inline control valve that limits the pressure to 110# so I went on to replace the sender and sure enough, runs great. That old sender had a date of May 2003 on it so this seems like a common problem on these machines. Thanks a lot Tazza for all the help. Paul
Not a problem, glad it was so simple.
