Hey guys we recently sold our 743 bobcat and bought a 773 f series bobcat. I'm having a problem with it and I can't figure it out. Used it the other day and every thing worked just fine but today when you start it up and unlock the hydraulics the 2 green lights come on on the left steering control. Now this is a hand control machine so no foot pedals. When you unlock the skid steer the boom will raise and lower but when you go to curl or dump the bucket nothing happens. Now when you dump the bucket the light goes out and when you let off it lights back up. When you curl the bucket the light goes out and then flashes and locks the hydraulics from working. Boom won't raise or lower so you have to shut down and restart. I have checked all the wiring plugs and can't figure this thing out. It was working fine yesterday and now this. Any possible fixes any one can think of? I counted the number of times the light flashes on the left steering handle right light and it flashes 5 times then has about a 1-2 second pause then 5 more flashes and keeps doing that. The bucks beside the seat every thing is lit up except the one for the valve lock but it does not flash.
