I have had a refurbished RCX400 10" for 4 weeks and it has worked very well. Last night it was having some problems tracking. This morning I was going to check all the settings in SETUP. I hooked my power source (12V 7.4AH deep cycle battery) to my scope and turned the scope on. The power light did not illuminate. I unpluged everything and tried again with no the luck. I did charge the battery overnight, so I know it was fully charged. I even checked it with a volt meter.
Any help/suggestions will be gratefully appreciated.

I dont know if this telescope has in internal fuse.
I hope you had an external fuse on it if so check that.
Also confirm that the battery has a good charge.
When not on a load it may show full but with a load it may be dead.
You can try the yahoo group for the RCX scopes and see what they know as im not vary familiar with that model.
Regards
Mark

Thanks Mark
The battery is charged under load. I had assumed that the RCX would have an internal fuse/circuit breaker. No such luck.
Not much luck with the Yahoo only one post. I have had the bottom panel off the control panel and am beginning to suspect to ON/OFF switch.
Anyone else have any Ideas?

It could be the power switch or something in the power panel itself.
Hopefully someone on either group can help.
Also you may want to contact DR Clay as he is familiar with the workings of the RCX scopes.

Found it!!!!
It was a broken circuit on the circuit board under the control panel. The circuit looked as though it has been overloaded sometime in the past and had melted 80-90% through. My moving the scope along a gravel driveway on a scope buggy probabley did it in. Luckily I was able to repair the scope and it is functional once more.
While I had the circuit board out I checked a small 3V battery that was only putting out 2.1V. I suspect this battery is used to power storage for saving GPS and Park data when the scope is turned off. Mark do you know what the battery is for?
I feel very fortunate for having found the problem and for being able to repair it. I think I will go say a few prayers.

The battery is used to store the info of time date and I believe GPS information as well as for holding the park position info.
Im glad you were able to find the problem.

The battery is a CR2032 , and only keeps the GPS's internal almanac and clock alive.
It does not have anything to do with "park" information, that's stored in the
Autostar II's own FlashRam.
have fun
