The Polyphaser just has MOVs inside. Did you purchase it new. MOVs
degrade over use and often fail shorted. You can check for continuity to
ground with an ohm meter, there should be none. You can also open the
back and look for obvious failures. If the protector still looks good and
you have it wired correctly you can run the rotator and check to see that
the voltage is present at the terminals.

Subject: [TowerTalk] Yaesu G-2800 Rotor + Polyphaser Rotator Protector
Issue

All:
I installed a Polyphaser rotator control line protector on my Yaesu G-2800
rotator and found that the rotor would not work. The rotor controller spun
erratically when I changed heading and the rotor itself would not spin.
I disconnected the line protector and the problem went away. The protector
is the shunt type 8-wire unit shown here:

The Yaesu rotor uses 6 wires which I connected as per the instructions
leaving 2 terminals free. The protector was grounded and mounted to a
copper plate inside an entrance panel.
The rotator seems to be working fine, but I wonder if I caused any damage?
Any ideas?
Tony
