-   My Ryobi CTH 1202 Charger wont charge batteries. I took it apart and the 250V 500Ma fuse was blown. I put a new one in and as soon as I put a battery in to charge it blew again. Does anyone have any suggestions as to what the problem might be or how to test/troubleshoot the problem. Any and all help is greatly appreciated.-   paniollo

Take your charger out on a boat and dump it into the sea. Then go to the store and buy a new one.
I have two 18volt chargers doing the same thing. I have had them apart and it seems to be the transformer not pushing any power thru. If you can find a transformer that fits and has the right voltage that should fix the problem. From what I can make out if you leave the battery in for too long on charge it cooks the transformer. Hope this helps

I lent my Ryobi 18 V batteries and flashlight to a friend during a power failure. When they were returned, both batteries would not take a charge and the green yellow lights show on the charger. Are the batteries toast, and is the problem that they were charged before they had a total discharge?
