Ok I started working the problem tonight. I would first like to thank, Al Wa4sca, Stan W1le, and Jeff N3qo, for some ideas on what the problem might be. What I found so far is an open between 4 5 and 6. Any combination of the three is open. So I'm assuming I burned out the motor windings in the azimuth rotor to cause an open. I'm also assuming as the rotor is less than 3 years old that it doesn't have a fused link? I went through my parts bin and found a working Yaesu G-450 rotor. I wonder if the 450 and the 5500 azimuth rotor use the same motor, did anyone try this?

Starting to put my satellite system back on the air. Now having another rotor problem. I think what happened is that after Hurricane Irene passed by, everything was working. Later that morning a surprisingly strong wind gust after Irene passed by blew my sat array over. I was unaware of this and when I tried to work a sat I had a very weak signal. I went outside to check the antenna system and found it laying on the ground. So what I think happened is that the rotor was trying to turn while the antenna was on the ground and burned out something in the rotor. It is not a cable problem, it is definitely in the azimuth rotor, elevation works fine. I swap cables and this showed the problem is in the az rotor only. Anyone have this same problem? I'm going to take the rotor apart this weekend and would like some ideas before I start. Any electrical test through the cable from inside the shack to determine the problem would be much appreciated :-) 73 Jeff kb2m _______________________________________________ Sent via AMSAT-BB@amsat.org.
