Hi all,

This is a strange one for me that I can't seem to solve.  My elevation rotor
still operates up and down as usual.  However, when I hold the "Up" key when
the elevation starts at 0 degree's, within a second or two the meter shoots
up to 180 degree's.  However, if I keep holding the "Up" switch, the
elevator still goes smoothly as usual but the meter stays at the 180 mark.
When I hit the down button  the elevation meter  jumps back to 0 degrees in
a second or two.  This while the rotator is still smoothly declining.

I retinned and rehooked the cables at the box entrance thinking one may have
shorted from box movement.  Same result.  Would a short somewhere down the
line cause this or do I have a bad meter or box switch.  My mast mounted
elevation rotor works fine as far as functionality, just can't get the
readings on the meter.  Of course, this throws off the LVB Tracker.

Any other thoughts?
