John? Can you post a quality picture of the burnt out board and lets have a look if there is any chance of repairing it.

 

If it's not broke, fix it until it is

It might be better to get the mount checked out by an authorised Celestron dealer. There may have been a reason why the original board burnt out which was not evident when you plugged in the replacement and then caused the new board to also fail.

Peter I was just thinking if I can see what has burnt out I may be able to figure out why, after all there is no point in replacing the main board if you don't know what caused it in the first place. I wholeheartedly agree with taking it to an authorised dealer, but if you have a working board to go with it that is a big cost saving.

If the new board burn out as soon as it was connected, it sounds logical to assume there is a fault somewhere in a component or the wiring. If you have a Volt meter can you check the incoming voltages to the board and report back, I am sure some of our knowledgeable electronic buffs may be able to comment, once this is known. A good electronics repair Engineer may well be able to repair the boards for you, if you can find a small company which deals in such things, it is certainly, I would think, going to be cheaper than $190. Hope you solve the problem

Yes I have spoken to previous owner he daid he took boards out to have a look and didnt know what connections when back he said he got confused so this is where im stuck trying to find out whats the wright layout of putting connections on the wright way as I have new board on the way and dpnt want to burn this one thanks all help needed fast as daughter is quite upset 

[roblegion]

Please post a pic so we can see which board it is. If there are 5 connectors they are:

ALT = Dec Motor

AZM = RA Motor

SBB = Hand Controller connection

AG = Autoguider or Aux port

If there is one 2 pin connector left this is power in.

You sound spot on there I will post pictures as soon as I finish work much appericated

Hi all.  Really appreciate this post because I had the same problem.  At the beginning I never got the alignment, if I selected goto right the telescope moved to left...

Years ago I connected in a wrong way the cables DEC and Hand Control in the mount, its connector are RJ similar, then the motor board was burned. THIS IS VERY important to connect properly the cables and use a flag with tape to help me in the nights. After I replaced the motor board with a new from Amazon twice, the first burned, the second time I connected internally the new board with the same configuration of cables connection as the old board, but again moves in wrong way, then I tried to update the firmware due to never the alignment works, so I think the update destroyed the software, then hand control said that the motors were not found; the third card worked but again never I could got the alignment, the reason was that internally the board cables were connected in wrong way, maybe since fabrication.

The great solution was until you posted this theme with your pic. I could connect it properly then now works fine and the firmware update worked. Now, for first time I got the polar alignment, finding the stars and nebulae. I am happy for this after of years trying and trying how to solve the issue.

Thanks a lot for this.
