[RE-wrenches] Watsun problem

[Ray Walters]

Sounds like you are driving it too far to the East.  You may need to 
rotate the tracker on the pole towards the east, and then reset the 
limit switches.
Also, don't have the limits more than 180 degrees total, or you start 
asking for trouble.  It can try to do the morning reset back around to 
the North, if the azimuth is set to wide.

So the battery voltage is always at 24V. The tracker will run fine for a couple days then it will get stuck in the east facing direction. I can make it track by switching the control box to "Manual Control Mode" and then moving the array in any direction for a second or two and then switching it back to "Automatic Control Mode". It will then track for a couple days and get stuck in the east direction again.
