The line filter light is indicating that the line filter is plugged. Changed the line filter. The old filter appered OK but changed it anyway. Started it no change still flashing. Machine operates normally. The pressure switch on the end of the filter housing is showing open per meter when shut down and still open when running. The switch was remove and metered. It shorts when activated externally when press in and opens when released. The switch looks to be a differental pressure device.The wire to the pressure switch has 6.6 volts dc when the machine is running. According to the electrical diagram the instrument cluster is looking for the pressure switch to apply ground to give an indication of the line filter being plugged or when cold the hydraulic oil needs to warm up. Rung the wire back to the instrument cluster and it is good. So, is my instrument cluster the problem or am I missing something?
