I am trying to build a heated jacket for winter riding
I am wanting to use a potentiometer to controll the current thus the amount of heat I already have the step down converter going from 100volts two 12volts at about 4amps I tried to just wire a potentiometer in line and turn it up and down but I think the current is still to high going threw the switch because I can see it spark inside the switch when I turn the knob can someone tell me what I need to do to make this work.
