These belts ensure that the alternator is capable of spinning, which would generate sufficient amount of electricity for the battery in the car. That is why you need to always put the belt in good shape to avoid other problems while driving.

  • Cables

You need to check the cables for any loosening and its general working condition. When there is loose cable, it would affect the spinning of the alternator, which would not generate enough charge for the battery. You might probably need to tighten the loose cable to avoid more severe problems. Also make sure the electrical cables are well connected and tightened firmly into the battery connector. Check the wires for any damage as this could be the reason why the battery isn’t getting enough charge. This could also cause the battery warning light illuminating on your dashboard.
