I recently picked up a Emotator EV700X elevation rotor.. Everything works fine, the rotor rotates on command via the control box,.. All lights work . There is one major problem,, The indicator needle does not move although the rotator works. Does anyone have any suggestions as to what the problem could be ?? I don't believe this EMotator is being produced any longer. The rotatpr itself is built like a tank and works great. The shaft for the needle indicator is not turning at all .. Thanks for any help...
