I lost my adapter to my keyboard and I need to find either a substitute or a new way to turn it on without the adapter, HELP!!!.


Some Casio Keyboards use 9V DC (center negative) others 12V DC (center negative).
If check what voltage your Keyboard use. Generic AC adapters are usually center positive. So you have to invert the wire with a new DC plug to make it center negative,
Easiest is to buy a Casio ac adapter made for your keyboard from a Casio retailer.

I,m trying to find charger for a kraft tech 18v cordless drill. Can anyone help?


Hello,
there are two components require to charge a kraft tech 18v battery.
A power pack (power suply) and a battery station. The power pack says 24v DC 400mA but produces 34v DC at no load. When the power pack is connected with the battery station a green led lights at the battery station and the battery station produces 32.4v at no load( i mean without put the battery on to battery station. I believe that if i put the battery at the battery station the voltage drops to 24v DC, which is the voltage that the power pack says. I'm sorry but i can not measure the voltage that produced from the battery station when the battery is on it because my battery is dead and has shorted elements.
I hope that was useful.
Greetings from Hellas (aka Greece)

Battery Packs for Powerware 9355 UPS


The Batts can be charged externally, then refitted, usually I extend the DC cables so I can work with the batt outside the unit. This is ONLY to be done if you understand the risk and what may happen if you get it wrong.

Batts are always live and can cause fire/explosion/severe burns if shorted!
IF YOU ARE NOT SURE THEN GET SOME EXPERIENCED HELP!

OK so the UPS will not normally recognise a very low batt pack, that is the reason you can not start the test, this test will back of the rectifier so the batt pack takes the load for a short period.

If the batt pack is out of range then this will make the load go off, so the UPS is designed not to allow the test,unless the batt is at the right level.

If you can get the batt pack up close to normal then the unit will recharge it to full.,Wait until it is fully charged before testing.
If this is sucessful the cyle the batt a few times allowing it to reach around low batt warning before recharging. This will assist the batt in recovery. During this process if possible monitor with a test intrument(fluke 123 or 43B will do) the batt pack discharge curve , once the batt pack has dropped to its charge level from float, it should be a smooth decay.
depending on the state of the batts you may be ok, if there are weak ones in the string then you may have to replace all of them depending on the age of the batt pack.

MAKE SURE YOU ARE VERY CAREFUL WITH BATTERIES, THEY ARE VERY DANGEROUS, AND ALWAYS LIVE!

Check you manual for safety procedures, BEFORE working on Batteries.


hope this helps

thanks for using Fixya

No refund


These things happen. Unfortunately just the cost of modern technology. That is why battery business is increasing every day. More batteries being used and used up. You can purchase a replacement on buy.com with free shipping for about 23$. Just follow this link

Supersonic SC-299TDVD


Battery back needs to be connected to the DVD player when charging. connect the batter pack to player. Run the DC/out from the battery pack to the DC/in in the player. plug the charger into the wall.

if that does not work, you have a bad battery

E200 Serial Port URGENT


You will not find any matching connector to connect the JK-744 host adapter for attaching to the 9 pin serial port on the pc. If you want full pinout details please contact me directly. Please do include some information on what you are trying to achieve. Maybe I can be of help in that department. I however have a feeling that trying any micro surgery on the JK-744 or trying any kind of non Casio adapter is likely to mess up the JK-744 device itself.
