Bobcat 864 Oil Pressure Warning after 3 months of sitting.

[Kitt]

Hey guys, I have had no choice but to become a competent wrench on the Bobcat I have, and have been able to work through several issues (with photos and conclusions) on here... This is the latest: Bobcat maintained well, ran great when I left for a 3 month trip in May. Upon arriving home, My bobcat started right up with a pump of the fuel prier and a battery charge... EXCEPT I now had an oil pressure warning light. It is the constant beep and shut-down symptom, but engine runs and sounds healthy. I believe the 864 uses oil for cooling as well, but the first thing I did was an oil change (since levels were low) and pulled out just over 8 quarts. So, in the last 200 hours, no major consumption. I am hoping a sensor went bad, or mice got into the wiring somewhere - but am looking for some advice or photos of the troubleshooting process you pros would take! The machine was stored inside, and has never displayed this light before. http://i245.photobucket.com/albums/gg49/calfranch/Bobcat/T190/Warninglights_zps99aebbeb.jpg Summary: Bobcat ran fine, was stored indoors for 3 months, upon start I now have an "Engine Oil Pressure" Light is blinking until machine shuts down. Performed fresh oil change and filter - same symptom.

I'm guessing the oil pressure sensor is either the red or blue circled sensor in my picture... A pointer on that would be helpful as well: http://i.imgur.com/m9fJeh3.jpg

I think the pressure sender is the blue circle, the red one should be temperature. Temperature senders are generally in the head, pressure is in the block.
Hopefully it is just a sender (its not uncommon for them to fail), to know for sure, you can remove the sender and install a manual gauge to see what the figure really is.
