Problem fixed. First thing I checked in October before I headed south for the winter was the rotor cable, and connection. All looked good. After checking the cable with input from other setups, it became apparent that I had a bad connection between the rotor and the control box. With that info in hand I climbed up to the rotor and swapped the az/el cables. Azimuth was then working ok, indicating a 100% probability of a az cable issue. I then inspected the cable more thoroughly and found , behind some bushes where I had about 30 foot of it coiled up it had been cut in two places with maybe a weed whacker. I think the gardeners helper cut it and then stashed it behind the bushes to hide the fact. Anyway all is once again well in kb2m/2 satellite land. All I need now is a 70cm pre amp for up here....
All have a Happy New Year 73 Jeff kb2m

Thanks for all the info. I think I narrowed it down to a bad cable(or connector at the rotor) between the control box and the rotor. From the info gathered the rotor itself appears to not be the problem. I will get out there tomorrow and do a quick cable check, and will know for sure.

Jeff,
I failed to paste in the readings on the last post.
G-5500 rotor
E-4 DOWN #16 WHITE E-5 UP #16 BLACK E-6 COM #18 BLUE
E4 to e5 = 7.2 ohm E4 to E6 = 3.9 ohm E5 to E6 = 4.8 ohm
A4 to A5 = 9.7 ohm A4 TO A6 = 5.5 ohm A5 to A6 = 5.5ohm
A-4 LEFT #16 WHITE A-5 RIGHT #16 BLACK A-6 COM #18 BLUE

I'm back up here in the frozen north for the holidays and today had some time to work on my G-5500's azimuth problem. I took my 5500 control box up here with me from my station in Florida to help test. Now I've got it down to the Azimuth rotor itself. I used to have a repair guide for this rotor, but I haven't worked on one in many years and 2 moves ago and can't find it anywhere including online. Does anyone have a copy they could email me? I have the cable disconnected from the rotor control box. I'm interested in taking some meter readings to try to determine what parts if any to order from Yaesu. Thanks in advance.
Everyone have a very Merry Christmas, happy holiday, and a HNY.
