Just bought a bobcat 773 F. Drove off the trailor and 15 minuste later no hydrolic.---blew a hose. Replace hose and fluid. no lift or tilt or foreward or reverse. jumpered three wires to lift arm switch and got foreward and reverse but no lift or tilt. Jumpered seat switch out__ nothing. Checked fuses and thinking maybe brake switch. Panel with guages has no backlight. I can shine flashlight on it and read it some. Turn key on --beeeeep and b-55 shows where hours are. I think that is what it says...not sure.Any help is deeply appreciated.
