MOVs degrade with each lightning event and will eventually fail. Typically
they fail shorted. I have had many PolyPhaser rotator protectors fail or
start to leak. Often the MOV damage is visible when you open the cover. It
is certainly easy to disconnect the device to test the rotator and MOVs.
The MOVs inside the Array Solutions NEMA enclosure are easy to replace.

Does anyone on the list have any experience with this rotor control line
device going bad? I'm working my way through a process of elimination to
find out why my TailTwister no longer indicates direction nor will turn my
beam. I've replaced the auto-start capacitor (no change) and hooked my box
up to a known, working rotor. That works just fine: releases the break and
turns the rotor. The surge protector is the next item in the line of
inquiry.
Thought I'd post this before disconnecting all the wires from the SP and
reconnecting them in their proper order of color coding.
TIA and 73
