Autostar 497 Shuts off While slewing
Posted 16 March 2013 - 10:41 AM
I have a LX90 8"LNT on a wedge and have recurring problem with my 497 handbox. Whenever slewing anywhere within 10 degrees of zenith the handbox will lose power. It's not cord wrap as I have led indicators on the cables stating it has power and the power buttin LED is still lit. I have to turn it off and wiggle the cables to the handbox and base and turn it back on. It's frustrating because it loses it's position everytime and I have to go through polar alignment any time. I'm curious to see if you guys have any experience with this problem or know how to fix. I think it may be the connection between the fork mount and the cable. Is it possible that the board is moving around on the inside of the fork? I'm at a loss. It's ruining my evenings.
Thanks in advance!

It could also be a cold solder joint on a socket on a circuit board inside of the RA or Dec motor housing.

My suggestion would be to carefully look into the HBX connection on the mount using a strong flashlight.
And a curved pointed tip tool, lift the brass connector wires up and away from their connector.
Pry them and lift them out of the channel they lay and make them stand up, just a bit.
Of course power will be off!
Then re-insert the cable end and you will find more resistance, press the cable connector into its latched position.
This should solve the problem.

Give it a try with perhaps a small wire with a hook formed on the end.

The connectors were loose and corroded. I bought the mount used, and the guy I bought it from used to leave it outside.
He swore it was fine. this is why I never leave my stuff out!
I have a Compustar 14 that is 24 yrs old and is mint condition!
I have extra sockets if you need one. De solder the pins and use small solder, and be careful.
If you need one just let me know. It is a lot cheaper than replacing the electronics.
