This might be a stupid suggestion, but did you check that the clutches are fully engaged? You might see erratic behaviour if they're not, but probably not nasty knocking 
Anyhow, ignoring the nasty noises, set the mount to the home position (white painted index marks aligned), power it on and set it to time zone 10, it should remember the lat and long from before, and enter the time with DST yes. Then follow through with an alignment, say auto 2-star align and select a couple of stars....doesn't matter which. Select center and align for each and it should say align success...it will just believe that it is near-perfectly aligned and should slew to where it believes stuff is. Whether it's pointing in the right direction will depend on the offset from a correct alignment and time values. Btw, you did enter the latitude and change N to S? Sorry if it sounds patronising, it's not intentional  |
Don't worry about sounding patronising...I'm up for any suggestion that might detect the problem.
Yes, I double checked the lat and long, particularly whether E and S. Also, there's a tracking 'mode' which can be set to "EQ-North" or "EQ-South". I've checked that as well. I followed the manual pretty carefully, so yes, timezone 10, lat 35S, long 149E etc, daylight savings. But I would have thought that any error setting these up would result in wrong pointing, but not result in different behavior on each power-up (repeating exactly the same steps).
As you did, I also had the same thought about the clutches also occurred to me. I tried with the both with the clutches fully "tight" (as tight as I was game to have them), but also slightly looser.
The other thing I might try is to repeat the experiment without any weight on the mount, i.e. no OTA or counter-weights.
