I bought a sg-9120 motor a couple months ago or longer and remember shortly after buying it a thread here that discussed the fact some of the chart information for the declination setting or one of the other settings was either wrong or the indications on the motor themselves were wrong. I am now ready to install the motor but cannot find that thread particular thread. Must be putting the wrong "key" words in during my search. Anyway if anyone knows the thread or knows what adjustments I need to make during the install that deviates from the instructions, I would appreciate the help. I seem to remember Brian at SatAV made a comment in the thread. Thanks in advance.
