Thanks! I think I'll try upgrading my battery before I start messing with
the worm gear adjustment. Do you think 35AH is big enough (just mount, no
If I still have trouble, I'll talk with Howard and Wally...

my battery voltage getting low (I have one of the little Kendrickbatteries

worm gear mesh (since it always seems to be the Dec axis, and you recall
had a slight problem with this a couple of months ago).Those batteries don't last very long. What you need is a big marine battery
from one of the big box stores. Cost is around $45 to $65, so it's not
expensive. Reason why it seems to stall when using Dec is that RA is always
running the mount in sidereal mode. When you add Dec, you are increasing
current draw because now both axes are drawing power. This may put it above
threshhold of the battery, where it then begins to die.
