Re: AC power supply for CGEM, no response fault code

Nick,? ? ? The ma rating your seeing is just how much current it can supply if the scope needs it. As long the new supply is equal or higher in current (ma) as the old supply it¡¯s fine. As long as it is recommended for your Celestron ?mount, the voltage should be right and that¡¯s the important number. ? ? I had a very similar problem with my mount and it turned out to be the cable going into the hand controller was coming out of its pc board socket. Just carefully remove the four screws from the back cover and look for the wire coming in. ?Carefully push the wire connector back into its socket . if ?it has come completely out of its socket be careful to line the pins up with the holes in the socket using the edges of the connector for alignment. ?It may not be the problem but I have seen the same issue in three controllers and it fixed it every time so good luck and enjoy your telescope!

? Hi Everyone,
New member here. I¡¯m taking my time learning my new (used) CGEM mount. It was purchased second hand in late December and its seems to be finicky. It¡¯s giving me a ¡°no response 16 /17¡± error. What¡¯s weird is it doesn¡¯t do it all the time.?
The code came up a few times while using my deep cycle battery. I decided to try with the included AC adapter. Again, sometimes it works, sometimes it doesn¡¯t.?
I thought it could be possible the deep cycle cell AND the AC power supply could be bad or at best going out around the same time. The mount is suspected to be made around 2007-2010.?
So...I purchased a new power supply which brings me to my question. The Celestron new power supply is 5000mA compared to the one that was included with the mount is 2500mA. Is it safe to plug in the new power supply at the higher mA??
I don¡¯t want to make a mistake so I thought maybe someone could lend some advice or maybe had a similar experience.?
See attached. <FC780F87-B1B8-406F-84EE-6A882A1CB806.jpeg> <28F56882-8FF8-44E8-A0D2-D8E2AAC7585E.jpeg>
Any help is appreciated! :)?
