Why the cordless drill motor not run? Answered
I have a problem with the motor of the cordless drill.
I converted my cordless drill from Ni-Cd battery to Li-ion battery 12v6 using the protected PCB as this image: http://www.ultest.com/shop/image/cache/catalog/Power-Modules/HX-3S-A01-1-500x500.jpg.
After connecting the 3 cells Li-ion battery to PCB, I measured the voltage at P+ and P- is 12v.
So the connection between the battery and PCB is correct!
Try to connect P+ and P- (from PCB) to the positive and negative terminals of the motor, then the PCB cut-off voltage at the output pin.
The reason is the 2 terminals of the motor is connected (using the Digital Multimeter to check).
How to resolve this problem with the motor working properly?
