If you don't have 12V on the brown wire when switched to 4High mode, check to see whether there is voltage on the TOD yellow (or is it yellow/brown?) wire. If there is, the TOD is probably blown (assuming no wire or connector problems).
If there is not, the GEM is not outputting this control voltage to the TOD (again assuming no wire or connector problems).
OK, I did this...
I have 12v on the brown wire at the TOD when I select 4 High (no voltage when I leave it in AUTO)
I do not have 12v on the yellow wire at the TOD in any switch position
Suspecting the GEM?
