i dont think it is tyhe speedos, but the arent clicking or do anything, what i mean by getting voltage to the motors is there is power at the positive and negative wires coming out of the drill motor

yes it was slipping at wigan and to solve this my dad was told to lock the torque by putting a screw through the black housing with torque numbers on i know this isnt the right name but any way

if it was what you suggested grant how do we solve it?
