A 12 V DeWalt power drill has three contacts. B+, B- and a third pin which is either a thermistor (TH) or an identifier (ID). I have connected 12 V to the B pins, and the tool LED lamp flashes momentarily when tool is turned on, but tool refuses to work. I suspect this is related to the 3rd pin.
What must I supply on the 3rd pin to get it to work? This may be a static voltage or an analog signal.
Appreciate all information.
