We've been using our STT-8300M camera & CCDOPS for the last 2-3 years with the Y- relay turned off with no problem. Polar alignment with our pier has been good enough, we turned it off due to stiction & backlash problems. Recently we turned it back on to use with another program and tried to calibrate. The Y- relay now does not seem to work. The new program does not have the option of turning off any relay. So we can't go further without calibrating. Using CCDOPS, while using "FOCUS", we pushed each button N,S,E,W and it did NOT move in the S direction. We unplugged the 6C cable from the camera, shorted out pin 5 to each of the pins 1-4, and the scope DID move in all 4 directions. So very confident the scope & the cable are good. LEDS on the side of camera DO come on when each button is pushed, and the scope moves in the N, E, & W directions, but NOT in the S direction. Using my multi-meter, we measured resistance between pin 5 (common) and pins 1-4. I've attached a PDF of what we found. The readings between pins 5 & 3 were jumping between 1008 ohms & open while the S button was pushed. The readings between pin 5 & pins 1, 2, & 4 were 42 - 44 ohms. I'm aware I'm reading through a solid state relay, and not just through dry contacts, but the readings don't seem to be right. They should at least be consistent between pin 5 & the other 4 pins. Any help would be appreciated.
