If the Battery Light Comes On, It Might Be the Alternator's Fault

Model: (Various brands) Various
Part: Warning light – error code

Video tutorial

If the battery light comes on in your vehicle, it is not a battery problem, but it means that the charging is inadequate. How is the battery charged in a vehicle? Attached to the engine is a component called the alternator - a fairly simple component - made up of a stator and a rotor, which together generate current and electricity.

This component is connected to the auxiliary belt, and as the crankshaft turns, it spins the stator and creates a magnetic field generating electricity. As long as this component works, it keeps the battery charged, allowing us to use the electrical services of our vehicle.

So, when we see this light, it could mean that the auxiliary belt has broken and the alternator is not charging, meaning the car will run until the battery is depleted. If the auxiliary belt is intact, then the problem lies with the alternator itself.

How to Remove the Rear Seat of a Hyundai Tucson?

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
