hi, check the connectors between the axle and the chassis , they may need cleaning , check the battery connectors where the battery connects to the chassis , looks like three large button holes .. make sure the frames connectors move easily and are clean.

Since this is a battery movement, replace it with a new one. There are several outlets online that offer these as parts - Clockit.com for one will have what you need. They come in different sizes, so you will need to measure the old one to get the right movement for this clock. I am not familiar with Sterling and Noble, but the website will give instructions for getting the correct part.

It is most likely the batteries

From the description of the problem it seems that the battery has gone. It is not the voltage only, it is the amperage/current as well. You can get 12 volts by connecting eight flashlight batteries too. But since the amperage is missing you can not light up more than a bulb or run a radio or whatever. Similarly, your bike battery is showing the voltage but when you press the self starter button it is no go because the self needs very high current which the battery cannot provide. And when you jump start it, it gets full current and the bike starts and runs. When you stop and cut off the current is missing. So, my suggestion is to replace the battery.

I think the existing battery will be a 12V 26Ah type. You can use any brand 12V/26Ah batteries. Make sure you are using the same number and you connect them in the exact manner and polarity as the old battrey bank.

If the load is dropped then there is a serious fault with the ups, even if the inverter fails, it should go to bypass and not drop the load.

Sound like a control fault, I suggest you need a ups tech.

This equipment has many dangerous parts inside. Batteries are always live and very dangerous. The boards are stuffed the surface mount components.

You need an approved service agent, who should be able to help

good morning ! to open your sterling watch,use knife for snap in case back of your sterling watch ! good luck !..

I have always found Nikon to be extremely good with spare parts.

Have you gone to a camera store and asked them to order in a replacement battery holder? This will not be an "on the shelf" item. The camera is 20 odd years old, after all! but I suspect that (after a long wait) you should get your part.

If the camera store will not order in the part, try contacting Nikon direct.

Good luck.
