Mikko,
There may be “oxidized connector pins” on the RA box,
and likely DEC as well. Disconnecting and reconnected the Y-cable probably
cleaned them up – a bit. Maybe try a contact cleaner spray on both cable plug
& socket, to ensure longer operation, since this seems to have been
the fix to the original problem.

Light I
never opened the Dec gearbox so I don't know what's going on there. When I first
connected the Dec side of the cable to Ra and had the Ra box open, the quick
rotation I explained happened. After I jiggled and pinched the visible wires
inside the Ra gearbox, everything started to work. This with the correct Ra side
of the cable was connected. I don't remember ever trying again with the Dec side
after everything worked. I'll redo all the testing and record them step by step when the mount malfunctions the next time. That way we know for sure. Now I have currently three nights without a problem so I don't want to stir the status quo. Again, when I opened the Ra gearbox, I did the mentioned wire jiggle and pinch so who knows, maybe that helped. - Mikko |
