Common Car Electrical Problems and How to Fix them

1. Dead Battery

A dead battery is a common issue which every car owner may face. There are various factors behind it including the battery getting old due to reaching its lifespan, excessive use of headlights kept on for a longer period of time, faulty alternator, etc. It can prevent your car from starting and can cause a lot of hassle.
Fixing Tip –

  • Ensure the alternator is not defective or faulty, you will need a professional’s assistance to get it fixed hence make sure it is in proper working condition.
  • Use the jump start technique. This will take jumper cables and another working vehicle. Connect the cables to the working battery of another vehicle and charge the battery.

2. Dead Fuse Box

A fuse box is the main fuse station that is responsible for protecting various other electrical components. Fuses protect these components by breaking the circuit if the flow becomes too high. This prevents damage and risk of fires erupting. If the circuit exceeds the flow, the fuse will blow and can interrupt the operation of other systems.
Fixing Tip –

  • Start by locating the blown face and replace it with the newer one with the similar amperage.
  • Be mindful of overloading the circuit and ensure you keep preventative maintenance intact.
  • Replacing the fuse is relatively easy, follow the instruction steps given in the car’s manual.

3. Faulty Alternator

An Alternator is a crucial component of the electrical system in the car. It is responsible to transfer the circuit to power the whole car when it runs and charge the battery. If it is faulty, it disrupts the system causing dead battery, flickering lights and overloading the engine resulting in its failure.

Fixing Tip –

  • Dealing with Alternators is complex as its mechanism is tricky and it includes several other components.
  • The best way is to call for the assistance of a professional and let him run tests to determine if it’s faulty or not.
  • If it is faulty, he will carry on fixings and replacements if needed.

Bad Spark Plugs

Spark plugs are responsible for properly igniting the engine by firing air fuel mixture in the engine’s cylinders. They carry a expiration period too and overtime, they can go foul which results in engine startup failures which affects the performance of cars.

Fixing Tip –

  • Bad spark plugs require replacement, there is no other way to address it.
  • It can be replaced manually but it is better to let it get handled by a professional so that he can properly follow the manufacturer’s interval while carrying out the procedure.
  • Upgrade to high quality spark plugs that can significantly enhance engine’s performance and efficiency, thus prolonging its overall lifespan.

Corrosion in Battery Cables

Proper electrical flow requires battery cables in optimum condition. Corrosion detected in these cables can severely interrupt this flow and can cause problems while igniting the car’s engine, dead battery and failure in performance. It happens due to proper exposure to elements and battery acid.
Fixing Tip –

  • You can manually address the corrosion by cleaning it with a wire brush and a mixture of baking soda and water.
  • You can apply battery terminal grease that can help prevent future corrosion.
  • Inspect and apply preventative maintenance regularly to avoid complete failure of the cables. If required, contact a reliable auto parts supplier to purchase the replacement.
