I re-greased my Myt tonight and now when I try to home, the Dec axis takes a nose dive for the ground while the RA axis seems to be correct. 

 

I have inspected all cables and sensors and they appear to be ok. I removed any excess grease and didn't see any issues with that. Any thoughts would be appreciated. I have posted in the SB forums as well. 

 

 

Thanks

Is it possible that the the DEC homing sensor cable was plugged in backwards?

That was suggested as a possible cause on the SB forum as well. I will definitely check it, but I kind of remember when replacing it, that it only went on one way. I will double check to be sure.

Just double checked and I can only see one way of putting the cable on. SB zipped tied it so I would have to bend the cables back a long way to put it on the other way around.

Ken not sure how to interpret that. Are you frustrated about my comments about my inability to put the connect on the other way around or are you just out of ideas?

No. No. I'm out of ideas...

 

I hate it when a convenient idea is slayed by reality.

Just in case anyone else comes across this thread, I spoke with SB this morning and the sensor connectors can only connect one way, furthermore there is a document about the sensor on there website which states the opposite. It is in fact wrong, at least with regards to the Mty. 

 

Still haven't found a solution but it appears it's either the dec sensor or the dec sensor cable.

Just to close the case. When inspecting the cable again I noticed a small but deep crimp in the cable right next to the zip tie you see in the photo above. It was not easy to see.  New cable is on order.

Ouch. I remember when I re-greased mine, I was pretty nervous about the wiring.
