Really Straight pictures. I guess you must know you need to unplug the mount from power supply, Dec Cable and Hand Controller.

 

Screws are numbered.

 

Enjoy  the pics and hope is informative to you.

Seems simple enough.  I have yet to have this issue with my mounts.

Thanks. Good to know info.

This one is worth a sticky with the mounts popularity.

Thanks.... 

 

Isn't it too early for an AVX to need this battery replacement ? Mine is maybe more than 3 years old and battery is still good.

If your RTC isn't working then there is your fix. Even my Losmandy G11 recommend to change it every 6 months but that change from mount to mount I guess.

No, I've had mine for nearly 2 1/2 years and had to have changed the battery once.  Also disassembled that same area to repair the power connector.  On that job, I not only re-soldered the wires to the connector but did an "upgrade" to keep the connector from spinning inside the housing which is what caused the failure in the first place.  I used a thick piece of hard rubber which was cemented around the connector in a "U" shape to keep it in one position.  Haven't had to open the assembly since.

This was very helpful -- my brand new AVX had a non-working RTC -- I turned RTC on and it would always come up Jan 2000 at 18:00:00

 

I took the battery out and checked it and it was good at 3V, so I reseated it, put everything back together and the RTC worked.

 

SO the battery was just not making good contact even though it was seated correctly.

Thanks for the post!

 

Mine never has kept good time, from one new moon session to the next it has usually off by a couple of hours.

 

It has not been a big deal to enter the correct time, but this will be an easy project for the next full moon period.

I'm  glad this post is working!

Question.  When the mount is hooked up to an external power source, is the RTC running off it's small internal battery or external power?

 

I didn't see any info on the RTC battery in the user's manual.

My first guess is that it is running off the battery -- my reason for thinking that is when my battery was not making contact, with the RTC on, it would come up with Jan 2000 at 18:00:00 when the mount was powered up and the time would not tick up.   That was the first thing I noticed when I reseated the battery and powered it up the first time after getting the good battery connection was that the time displayed was Jan 2000 at 18:01:02 and the seconds were ticking up (e.g. about a minute had elapsed after I had applied power to the mount)

 

But this is just a guess on my part.

i just changed my battery after reading this post. Now my AVX does not  to have the time and date reset every time i turn it on! Thanks! It also gave me the opportunity to tighten up the nut on the power plug in.
