1993 Bobcat 853 Aux Hyd issues.

[KOENIGS]

I have having issues getting my Aux hyd to work. I have power to the switch up top. But I get neither light to light up. On the main directional valve underneath it has a large hyd tube that runs across to the Aux Manifold ? There are 2 small solenoids on the Aux manifold, but None on the main one. There are wires (2 pairs Orange / Black and Orange with white / Black) that seem like their length is right to run to the plugs on each side of the main hyd tube between the manifolds (Power Beyond ? Should there be to Solenoids / Coils on the main Manifold ?

If I jump power to the Solenoids I get my functions, so I am guessing the issue is in this fancy expensive looking "Brain"

I'd check the fuses and connections before putting the control module on the junk pile. Hopefully it's as simple as a bad connection or fuse.

Check all of the green lights come on the module that sits to the right of the seat. All of those lights have to come on before it will operate correctly. If that checks out, then the switch is most likely bad.
