Blowing fuses in power supply

About a 6 year old Meade LX-200 telescope. Keeps blowing the fuse in either the DC power supply or the AC power supply when I turn it on.

    I have an LX200, 8 yrs old. The fuse in the power cord from either battery or wall socket blows instantly when turned on. The fuse on the circuit board is ok. I read the explanation, but I have no skills in electronics. If I could see it in pictures or bring the scope to someone, it would help. Please let me know.

One thing to check, would be the filter capacitator that is on the front circuit board. They are known to become shorted. The cap is fairly large, and may be mounted on the side of the circuit board that faces the front panel. Clip one lead, and apply power. If the fuse does not blow, then that is it. A second possible component, is the polarity protection diode, that is near the power jack, next to the fuse. If it is shorted, then the fuse will blow every time.

Yes you can just make sure that the power cord has the CORRECT pin polarity- you can order the 12 volt cigarette lighter style cord from Meade.

I have a 10 year old Meade LX10 with Magellan computer. Do I need a separate power supply for the declination motor?


No, just one--- this scope runs off of 12 volt DC battery like a car starter battery pack-- that has a cigarette lighter style 12 volt cable. This plugs into the power console on the telescope. You need the proper 12 volt cable which you can get from Meade and other telescope retailers--

My Meade LX-50 telescope has developed an electrical problem. When I turn it on it immediately blows the fuse. I tried disconnecting the drive motors, and it still blows the fuse, so I think the problem is...


A fellow by the name of Ron Sampson can repair hand controllers and main boards on Meade telescopes. He does very good work. All you need to send him are the board(s).

You can contact him by posting a message on the Yahoo LX90 or LX200 group forums.

Good luck-- by the way he repaired the hand controller for our astronomy clubs 10 inch Meade LX200, at a very reasonable cost.

I have a meade lx90 8inch 3 years old with autostar 497--when i try to raise the scope up it keeps drifting down also having problems with intermitant slewing on set up-both motors working ok


This is called "rubber-banding". Your scope needs to be re-trained.

So, setup a target during the day at least 100 feet away from the scope (200 feet would be better, Calibrate motors using the same power source you use at night, and Train Drives. Later after dark, do a Calibrate sensors on Polaris.

You should train drives about once per year, and calibrate sensors about twice per year.

You may want to update the firmware before you Train Drives. The latest version is 43Eg available on the Meade.com web site. You with need the Autostar Updater Software also available on the Meade web site under Customer Service---- Downloads. Version 5.9

No schematics out there for that model, although there are ones for the LX classic and GPS. The center contact is positive.
