IH 886 dash light problem...means what?

[RickB]

If you see the light when you depress the clutch, the MCV (multiple control valve) on the LH side of the transmission case has a pressure switch on it. Possibly you have a leak or the 12 gallon pump is getting tired.

Good luck

Once again, that particular lamp lighting whan the clutch is depressed is PERFECTLY NORMAL. Disengaging the main clutch also opens the dump valve spool in the MCV which causes the lube oil pressure light to come on. If that lamp lights with the main clutch engaged, THAT'S the time to start checking things.
