3: Will it work after this repair and adjustment?

It looks like the gearbox works now and it's much quieter, but the LEDs flashes, maybe an indication of too heavy load or too stiff gearbox. I have to adjust it one more time and also take apart the gearbox to see if some of the shafts are bent.

I will do a test as it is now, among test that's important to do is to let the RA axis do one complete revolution to see that it don't get stuck at some position. From this I will get more experience of what can be wrong.

If I understand it right the batteries in the mount will last up to 40 hours, the camera (Canon EOS 6D) battery will last 4 to 6 hours.

Update:
Now I use the 5 volt USB battery pack through the Star Adventurers USB port, the battery same as I use to the dew heater electric band.
