I have 763 hydraulic warning light is flickering changed filter and pressure switch. Still light comes on.
I'm not familiar with this machine but the logical next step would be to check the continuity of the wiring between the switch and the warning light panel and also to ground if it has one.
Sorry it is a Bobcat 763 skid steer
C, F, or G Series machine?
763 G Bobcat
763 G Series machine, triangle shaped headlights, right? On the G series right key panel there are three different warning lamps related to the hydraulic system, hydraulic charge pressure, hydraulic temperature, and hydraulic filter restriction. Which of these lamps are you seeing? On the standard key panel (keyswitch), it would be warning lamps 24, 26, or 28 The Deluxe panel (keypad) has the same function icons as the standard panel but they stay hidden and only pop up when the ECU sees a fault in the system.
It is the hydraulic warning light
the light is on left side where key is
Wait, you're saying the key switch is on the left side? That's not a G Series machine then. The G Series had triangle shaped headlights. If your headlights are rectangle shaped, you do not have a G series machine, it's either a C or F series machine. G series machines are completely different the C or F series.
Does it do it when it's cold and you move the arms quickly? If so, that's quite normal - filter goes into bypass with cold thick oil setting off the light... If it still does it when it's hot then I'm not sure where the problem could be...
