Came late to this thread.
Running slow, baring mechanical binding usually is caused by defective
motor capacitor in control box. Replacing it does wonders.

Hi Doug,
Before you do anything, what is the wire resistance? The manual says the
maximum interconnect cable resistance is...
Terminals 1 & 2 = 0.8 ohm
Terminals 3, 4, 5, 6, 7, and 8 = 2.0 ohms
According to a nifty calculator spreadsheet
(http://www.rst-engr.com/rst/jimsdata/wirecalc.xls), to stay under those limits
at 275 feet, you should be using at least 14 AWG (0.696 ohms) and 20 AWG (1.759
ohms) wire respectively. If you're already there, look elsewhere. Several of
the othe suggestions sound good.

Subject: [TowerTalk] HamIV Rotor sluggish
The rotor is on a tower and the run is about 275 ft from the shack.
What is the best way to get more response from it? At times I have to
rock the antenaa back and forth to get it to even move. I am sure it
must be voltage loss. Boost the voltage from the controller?
Doug, N4IJ
