That sounds about correct. I have an old Kenpro rotator, I will have to check the model and find the original manual. From there maybe I can assist. I had to replace the transformer for the elctronics in mine many years back. Rest of transformer was OK.
If you can get rotation but no indicator or dial light you might have the same problem.
Thanks for the reply.
Opposite problem here, no rotation, appears to be OC transformer,
no volts on the transformer o/p windings that give the 26V? o/p.
Have tried with rotator disconnected, just to make sure.
