[amsat-bb] G-5400B Rotor problem

[Richard Lawn]

I could use some help trouble shooting my only G5400B AZ rotor. I rebuilt
the EL rotor years ago. I replaced the entire system with a 5000 at home
and now use this old 5400 at the summer place. The AZ just quite working. I
suspect it's a bad pot but could use some guideance in troubleshooting as I
don't have access to my notes from the EL rebuild years ago. What
measurements should I see at the controller interface?

Good thing we are going home in a week!
