Houston, we have a problem
Posted 25 February 2004 - 12:56 PM
I've been in a bit of a fog with my sweetie in a major health battle. I'm usually much more careful around electronics.
Anyway, I haven't been fond of the HandController, particularly when using big fat gloves. So, I decided to build a little switch box which plugs into the AutoGuide connector. 4 momentary switches for pointing the scope. Easy to use with big fat gloves when it's cold out.
Checked the wiring. Fine. Went to scope, plugged it in and pushed a button on my new box. My hand controller suddenly went dead. I looked down at the connector where I plugged in my little box ... wrong connector. I had plugged it into the Aux 2 connector rather than the AutoGuide connector. I un-plugged it and tried normal operation of my scope. Error 16 ... then a menu came up. I pressed align ... Error 17. Shut off the scope and tried again, same responce. Houston, we have a problem.
I pulled the base cover, removed the board containing the connectors and pulled out my Fluke meter. Power supplies ok. However, Aux 1 and 2 connectors have 12v on one of the pins. So, my little switch box connected 12v to a signal line. poof! Scope's electronics are useless.
I called Celestron to try to speak to someone, but could only leave a message with tech support. So I did. Got a call later that day from a tech. I explained to the tech exactly what I'd done. I told him I know it's under warranty, but I did the damage and expect to pay for it. (I'm thinking no new EP's for a year) He agreed to let me send in just the HC and one other board, and said they'd take care of it. I sent them in last tuesday. Today I just received new replacements ... free of charge! Now, I call that great support! Thanks Celestron!!! I am very grateful!
In the meantime, I've been using the scope using the old fashion star hopping method. A great education.
Just wanted to share my foolish experience so that others will avoid this mistake, and to say Celestron support is alive and well.

Should I need to remove boards, etc...can you recommend a site I could use for guidance?
John, sorry it took a while for you to find this. There is no site that I know of. If you haven't had experience with of electronics, I'd refrain from trying to do this yourself. I do hope it's just a connection problem! Good Luck!
