I am wanting to know if anybody would know. I have a CDE AR-22R rotor and I am trying to find out how many volts does the control box put out on it? Because I have 3 of these rotors and they start working real good for just a few minutes while I am turning the rotor and then it stops and just humes. So I want to check and make sure the power supply isn't bad in the control box. Also does anybody know where I can find another motor or power supply for this rotor?
