I have a Dewalt DW972 12-volt cordless drill that has served me well for the last few years. Yesterday I dropped it off of the step ladder onto a concrete floor - NOT GOOD!. When I tried to use it again, it will still run, but seems to have lost most of its torque. The motor has the smell of a burned-out electrical motor, ozone smell.
I am wondering if, perhaps, part of the armature has been shorted out by debris that was knocked loose during the fall or if the brushes may have been damaged? I don't know that it is worth sending it to a repair shop, so I thought that I would try to diagnose and repair the problem myself.
Anyone have any suggestions?
Thanks in advance.
