Reviving a very old thread; Tried to power up my G11S Model 492 drive last night after 10 months of no use... Nothing! Absolutely nothing!!! So I had to play the dobsonian game for the night and push the mount around.
I got this mount in 2013-14 and the switch has always been a bit dicky, exactly as others have described below. But last night it didn't want to play the game, I was suspecting a more serious electronic problem actually.
So I found this thread, pulled the circuit board out of it's box and toggled the switch back and forth furiously about 50 times... Then it finally turned on! Oh how frustrating.!!
So I'm off to Jaycar to see if I can source a replacement switch....
