I have read several articles about converting cordless drill into corded drill.
I have an old Craftsman 10.8V NiCd battery. It comes with 2 batteries. One is completely dead and the other is 90% dead. I opened the battery, it is basically a bunch of NiCd cells connected in series. No circuits whatsoever. I decided to do away with the cells and convert it to corded.
I found a Switching Power Supply that outputs 12V/12.5Amp. I thought 12V is close enough and proceed to convert. But when I put it together, it didn't work. When I first press the trigger, the drill works great. But as soon as I release the trigger, it stops working. I have to unplug the AC and plug it back in only to repeat the cycle.
I read several similar posts but none reporting the same issue. I figured maybe it is because of the safety feature of the Switching Power Supply but I can't see why it fails only when I stop the drill. It is hard to find a P/S that gives out high current. I wonder if there is an explanation to the behavior and if there is a simple way to fix it?
