Sorry i miss read your first post, guess is was late last nite...
See this morning you say it does Not groan. I'm asumeming you heard some sort of Hyd noise when you operated the power bobtach switch normally. I personally don't have one of these. However if its like most of Bobcats elec/hyd controls, this is going to be a coil (cylindical shape, color of grade 8 bold , with 2 red wires coming from it) that slides over a spool, with a nut on top of it (in the center) holding the coil down. There is likely one for each direction of the cylinder. These coils are also used to control your front quick couplers, bucket leveling so finding the corect "pair" may take some investigation.
If you take the nut off the top, then the coil can slide off the spool in the center, when the coil is powered up, the magnetic field it creates will try to hold it on the on the spool, and you can verify that it is functioning.
A more common symptom would be either, 1; no voltage drop, hence no responce either direction, 2;voltage drop one way (with responce) and none the other dirrection.
It sounds like your coils are drawing power, I guess first, I'd try to check if its getting to the coils. One wire should be ground and the other hot when the switch is pressed.
As for the nut that hold the coil on, Tighten it VERY gently. (use a little blue loctight and tighten just past finger tight ) Also be very gental with the spool inside the coil. Dropping, banging or rough handling of any sort not permmited. There is a needle inside the spool that the magnetic field of the coil moves to open and close the valve. Any distortion of the spool can bind the needle and ruin the spool. ($90 each), dirt inside the system can have same binding effect.
They way both sides stopped responding it sounds like an power supply issue, if it was hydraulic, then it should be one side or the other. So I may be barking up the wrong tree, but I'd start with checking that the coils have power.
