Was reloading firmware into my Geosat Pro and after making some minor fat finger goofs, the H-H dish laid over and my system went down. Good grief, what did I do wrong? Not a problem since the system went into commission in 2007. The H-H motor eventually found the zero reference, but now it won't move in either direction. The orange light on the SG2100 tells me over current/limit failure.

Of course a storm is picking up and lightning bolts are flying. Thinking nothing of it, I pulled the dish down off it's pole (despite high winds and rain) and proceeded to take the system apart.

After pulling the motor apart down to the limit switches, I found a stuck limit switch. A light tap with a stick or bat could have made it unstuck, but I sprayed it down with contact cleaner and now it seems to be working fine.

Looking at my satellite settings, I forgot to set my Longitude back to 106W for USLAS. The firmware doesn't care where I live and was quite happy with 106E. So I guess the motor was doing it's best to flip my dish over and of course the limit switch did it's job but remained stuck after the fact. Oh well, the software warned me but the error message didn't make any sense. I'll have to pay more attention next time.

I thought these H-H motors had magnets and reed switches but mine has miniature cam activated mechanical switches.
