Hi everybody. I had originally posted under the Equipment forums but was advised to try here as well.. I apologize for any redundancy.
I'm hopeful that a relatively simple solution can be found with a bit of guidance from the knowledgeable folks on this board. I have a CPC 1100 powered by a Celestron powertank that has worked well for me up until the other night. When I went to turn it on recently, the little red LED on the switch did not come on, the handset remained off, and the powertank battery immediately turned off. The battery would not turn on again until I plugged it back into the wall charger, after which the battery resumed working normally (fail-safe??). Once again, I tried plugging the battery back into the scope, but the same exact thing happened. I tried using another power source (car jump starter battery) with a cigarette lighter connector, which again failed to power the scope. Considering both batteries seemed to be working well yet led to the same result has me worried that the scope itself is the problem. This scope is a beast and shipping it back to Celestron support would be a final option. I'd really appreciate if I could get help troubleshooting this problem. Unfortunately I don't own the AC adapter but I could buy it to help rule out the power sources. It's just that 2 batteries with 2 different cords have led nowhere so I'm skeptical. Thanks in advance!
