Have an ‘84 Altec AA600 boom truck. The controls at the bottom(on the truck) work the boom fine......the control from the buck,the pistol grip, when the safety is pushed in from the pistol grip the bucket turns to the left. Nothing else works from the pistol grip. One mechanic said it sounds like it’s bypassing fluid inside the valve and if the spool is bad then I will have wasted my money by not replacing the whole thing. I have found a whole valve replacement piece for 1600.00 but hate to spend that money if that’s not the problem. Does anyone have any clue what this sounds like?
