When I last checked it, I don't recall any discernable difference in
resistance in those lines. Note that there was no discernable speed
difference in one direction or the other before the lightening strike. I
wonder if the motor itself may have been damaged(?) Any thoughts TT'ers?

If it turns slower in one direction than another, I'd look at resistance in
the wire supplying current in the slow direction. The T2X has two power
wires, one for clockwise, one for anti-clockwise rotation. Using an accurate
ohmmeter, measure the resistance with between these two wires and the common
wire.  They should be the same. If they're not, it is time to find out why.
Usually there's corrosion on the connection at the rotator, which is easy
enough to fix.

 

This is outlined in a troubleshooting section in the rotator manual that
shows typical resistance and how much to allow for specific lengths of rotor
cable.

 

Good luck and 73,

Recently, my tower took a lightening strike and it appears to have taken out
the direction pot in my T2X rotator, I can still turn it, however, it seems
to turn slower in one direction. What could be the cause of this?
