Quote: On attempting to align...the computer/hand control (which oddly does not ask for lat/long input) asks for time information, asks which alignment (one star/two star etc.) ...I suppose it may be time to send it back to Celestron/Dealer???

Quote:Thanks for your help, here are the answers to the questions...Power supply is a 12 volt deep cycle marine battery that is essentially new and fully charged.I have only used one power cable...where would one find a better quality one (as I assume the answer is not celestron). I will need a good one anyway when I do get this sorted out. How would one look for broken wires (VOM?)Cracked solder may be beyond my ability to fix...but I am happy to look if anyone has a suggestion as to exactly where to look. Also how would i be able to tell if the handset is "faulty from the factory"? I am an Eq. noobie having used a Meade LX 90 for the last several years. I expected a learning curve, but this seems like more than I should have to learn!Thanks againDave

Quote:The stock power cable is a joke. The inner conductors are very fine and breakage would be easy. The symptoms would be intermittent like you were having. Low voltage could also be a problem. What were you using for a power supply?

Quote:... One thing to keep an eye on is the power switch itself. These have been notorious for going bad on a CG-5, when then do they usually don't work any more but they can break down internally and cause an intermittent re set like you saw. The full fix is to replace the switch (there have been a few threads on this and the replacement switch has been documented) but the easier way to mitigate it is to cycle the switch on/off a number of time (with no power) to "exercise" it a bit, maybe check it with a VOM (you don't want to see any resistance across the switch when it's on) and then to leave it in the on state and use the power plug to turn the mount on or off. ....
Quote:I selected Sirius...it started to slew, then after a few seconds of slow slewing, the computer wanted me to re-enter all the initial information, like it had reset, However, the telescope after a short pause (even though it was still asking for initial information again) continued to slew, paused again and then slewed to fairly close to Sirius.
Any suggestions for next steps (just buy an AP900 )

Quote:Dave,Running "fake" alignments indoors is a great way to exercise the mount and check out problems, it's warmer, brighter and there are usually more refreshments at hand.
