To T/S the meter, swap the elevation wires with the azimuth wires and see if the problem follows the swap. I hope you did not do what I did:
The contacts for the motor wires lay down onto the mete wires applying 26v to the meter ckt. Taking the control unit apart doesn't look fun. 73, Ed - KL7UW At 06:39 AM 1/28/2011, Dee wrote: >Bill, >Alan seems to have covered all the troubleshooting areas for this rotor- >Simple system. > >From what I have seen here on the BB, It is a toss up between poor >connections and Pot probs. >Good luck... >Dee, NB2F > >-----Original Message----- >From: amsat-bb-boun...@amsat.org [mailto:amsat-bb-boun...@amsat.org] On >Behalf Of Alan P.
