  • After releasing the negative battery cable from the battery terminal, you should disconnect the wiring harness. Do you know where the wiring harness located is? You’ll find it rear of the headlight kit. Does the wiring harness look clean on the headlight surface? Note that if the wiring harness is corroded, you should replace it certainly.
  • If the wiring harness is not entirely damaged, let’s play with it! Do you see a layer of corrosion in the wiring harness? Brush the layer with a pencil eraser. Besides eliminating corruption away from the surface, try dielectric on the wiring harness. It will prevent future erosion efficiently.
  • Have you had the operation done? Now, connect the wiring harness back again to the headlight socket, including the battery terminal’s negative cable. Turn the headlight ON! Are they working correctly? If yes, you are congratulated. If not, don’t worry. We have lots of fun aside!

We have two more techniques left. Try them out!
  • Do you own a non-functioning headlight? In this step, you should unplug the wiring harness. Remember connecting the negative lead to the battery terminal. You can quickly release the negative information from the voltmeter and set up to the negative terminal. Following the same strategy, connect the positive lead to the positive headlight wiring harness. Be mindful of the positive wire if power coming from it through the voltmeter. If all is functional, please replace the headlight bulb during the process. Then, turn the headlight’s switch on.
  • Now, look at the headlight wiring cable. It is situated back to the fuse box. If you see any intercepts in the cable insulation, detach the negative battery cable again. Now, you should cut the cord in two parts. One part goes before the tear; the second part goes after the tear. Use wire cutters to cut the cable. Now, connect each cable back to the point that you have cut! You should join the cables again with the heat gun and solder sleeve connector. Be careful of corresponding wire-like complimentary to a positive socket. Neutral to Neutral source! Melt the solder inside the sleeve connector. Try now. Hopefully, they work!
