I have a DeWalt DCR015. My radio charges my batteries and powers up with batteries, but when I plug it in, the radio will not power up. Any recommendations?

SOURCE: my used dewalt radio

open up and check fuses 

SOURCE: Dewalt dc011 won't charge or play on battery

could be a fuse in the radio. check with your local dewalt dealer.

SOURCE: Dewalt Dc011 radio will not work unless the battery pack is in.

check the fuse inside near the transformer.

SOURCE: hi ya my dewalt radio will not power on but still

You are lucky it still charges battery. Your transformer for the radio has a fuse on the winding, this has gone or the transformer has gone.

Check fuses inside. Check fuse and connections in plug. If this is a 110v radio there is one on transformer winding.
