Well after rebuilding a friend's 763 Bobcat's spool valve and stopping all his leaks my Bobcat has taken on problems. Seems like the BICS part of the valve has an issue as I cannot lift or tilt the bucket and when I move the pedals it seems to load up to relief pressure. Tomorrow I will check for voltage on the solenoid and see if it is activating. Coincidentally I have developed leaks on the tilt cylinder hoses so that's something else I have to fix. The odd thing is that the tilt cylinder seems to be going in the down position but not up. Something strange here!

Hoses and ram seals are easy enough, they do tend to go when the machine has sat for a while.
The BICS valve, ensure the light lights up on the BICS box, if not, it won't have power going to it. Its 12v, so you can jump it and see if it un-locks. You should hear a click as it disengages the lockout if you jump it. The coil or stem may be bad too.

This was a weird one. The bics computer was lighting up, but there was intermittent solenoid action. With the connector loose it always showed voltage. Once operating and current flows, it would fail. Turns out that something chewed the wire harness where it crosses the chain case and bare wires were touching each other at times. No fuses burned out, or other damage. SOme solder, wire and heat shrink tubing fixed the issue. Now to figure out how to keep the nibbling from recurring.

Maybe leave some moth balls under there
Has anybody ever tried these rodent repellent sprays like this one?http://www.deerout.com/critter/?gclid=CILe5vz9wZ4CFcx25QodkFq9ow
Around here mice are a real problem, mostly the little woodland jumping mice but a lot of field mice too, some plastics they really like to chew. Poisons, traps and electronic gizmos help a little but not enough most of the dead ones I find I think died of old age.

Ya know 12 volts won't hurt the stem coil of the BICS buit it really works on like 7-9 volts , a good way to check the coil is with a ohm meter , with the power plug disconnected and both spades of the coil probed with the leads of the meter it should read about 11 ohms , a good way to test if the coil is working is to remove it from the stem with the power wire still hooked up , energize the system and stick a screw driver or such threw the coil and it should magnetize and pull the metal object to the coil
Fishfiles - My coil actually had 12v stamped into it. The aux coils do run a different voltage though. It could by different from model to model though.
Ya right , I have seen 12 volts stamped on some of the coils , but the curcuit does send 7-9 volts thru it , why , I have not a clue , maybe some do run 12 volts I don't know
