Re: Question about American AutoWire Headlight Relay Kit

If you are still using the factory battery meter connecting the power source of the headlight to the battery or fuse link block will trick the meter into a charging display. The source of power for the lights needs to be on the other end of the shunt wire. Look at your meter with headlights on and alternator not turning. You should display a discharge. If you have connected to the battery side of the shunt, you will show a charging state rendering the meter worthless when headlights are on.
