Hi all
I have a Daiwa MR750 four motor rotator (three installed) turning my TH6DXX.
The problem is one of intermittent or no indication on the controller. It is
probably the rotator indicator potentiometer. As I don't have any circuit
information, I need to the ohmic value of the pot. The problem may also be
the plastic drive gear that drives it. The gear appears to have worn down
teeth. (Frankly I have the same problem but I am 66!!!)

Looking up Google tells me that others have had similar problems with the MR
750 and I would like to know of any solutions that anybody has come up with.
Perhaps someone out there will have a spare gear or pot in their junkbox?

The rotator is mounted at the base of the tower. I have had it apart two or
three times over the past few years and have cleaned the pot etc. It seems
to work for a few weeks and then goes off track and the indicator swings
wildly about.

Thanks for any help you can offer
