Hi Kitch. I think I've the same motor as you (maplains) and I find it only really works when you've got the polarity of you stb on H. This sends 18v to the motor where V only sends 12v. I've spend many, many hours abusing my box/motor/cables only to find this out. Even now with everything finished nice, I sometimes have to manually drive the dish with polarity of H because V can't do it.
I'll explain more if you need help. |
