The first thing I would do is check your connections, especially the one on
the rotator. Some, if not all, Yaesu rotators have a rubber boot on the
connector that does not effectively keep water out. If it's not that, maybe
the potentiometer in the rotor burned up.

Hi!
I have a Yaesu G-450XL rotor.
Last night somthing happend which may have been caused by RF feedback from
another antenna (vertical on ground).
I was transmitting on my 80m vertikal when all of a sudden my rotor control
box
start to go nuts.
It was aimed south and all of a sudden the rotor controllbox dial starts to
move clockwise towards north. When it reaches north I pressed down the left
button and could make it move all the way down to south again but when I
realased the button the controll box goes 3° left and right all the time
from
the center. It is moving like a ticking clock left right left right left
right
untill I power it off.
As soon as I power it on it starts doing the same again.
Now, when I went outside I noticed that the antennas was now almost beaming
north, while controlbox was set to south plus/minus about 3° in movement.
What have happend? And how do I repair it?
Please help.
