I have a Celestron CG-5 Go To, I believe its a 2002 model so its a bit old.

The mount started giving me problems several months ago, sence then the motor boards have been replaced and its pretty much a new mount!

Well I tested it out tonight and theres another glitch. The mount will randomly and without warning dew a fast high pitched slew for aabout a second or two, knocking the mount off alignment. I dont know what to do anymore with it, Ive had it refirbished and its still gives me problems all I want to do is get rid of it!

Help!

Since it's either been shipped or you've been inside the mount (replacing the MCBs) I'd bet you've got a loose or intermittent connection somewhere. If you haven't been inside the mount it might be time to get your hands dirty, and if you have been inside then you should probably go over your work very carefully, looking at all the connectors, pulling them off and re seating them.

Nope havent been in it, I took it down to Starizona and they re did the mount inside and it worked great right after, maybe something shifted. I will take a careful look inside.

sometimes low or a faulty pwer supply can make the motors do weird stuff.

One of the culprits can be the hand control connectors; put a drop of light oil or, better, electrical contact cleaner (Radio Shack) on the plugs and plug 'em in and unplug them several times.

Are the random slews on the DEC axis. If they are this indicates that the controller lost encoder feed back on the DEC axis. This would indicate that there is corrosion on the phone plug connections on the DEC cable. Remove the cable and inspect the cable ends for blackish corrosion on the connector tips. If there is some use and exacto knife to scrape it off. Also inspect the female connections for corrosion. Do the same for them if corrosion is noted. Also on the female connection look for a bent pin that could be causing poor connection.

Went to my friends house last night and we put all new ends on all the connections on the wires. After this it worked for a bit then gave a No Responce 17 code, we did all we could. Its now back to Starizona with it to see whats wrong with it now.

Is your power connection from power supply to mount super solid? I believe this error code is power related.

No Response 17 is a problem with the declination motor. It's not a very specific trouble code.

Per the Celestron Knowledge base it could be low power due to a weak supply or bad connection. Other possibles include the wiring to the motor, the motor itself, the motor circuit board, or even the hand controller.

Yep, sure can be that, no doubt about it. When problems like this crop up, I urge the sufferer to check both HC and power cables and to make dern sure the battery is good and fully charged.
