A car that suddenly won't start is certainly an annoying situation. This problem can be caused by many factors. One of them is a weak battery.
To overcome this problem, this time otomodify will discuss 5 factors that often cause and solve the car starter to suddenly die.
Weak or damaged battery
The battery is the main source of power for the car. A weak or damaged battery can cause interference with the electric current that is the source of power for the car. This causes the engine to not start properly or experience problems. Some signs of a weak battery:
- Dashboard lights are dim or not on at all
- The horn sounds weak or doesn't even sound
- The car starter sound is weak or only makes a 'click' sound
Solution
- Jump-start the car using jumper cables and a battery from another car
- If the battery has expired or exceeded its usage limit, usually more than 2 years, replace the battery with a new one
- Make sure the battery terminal cables are clean and not loose.
Problematic starter dynamo
The dynamo in a vehicle functions to turn the engine on for the first time so that it can start. If there is a problem with this component, the engine will not be able to start even though the battery is still in good condition. Common causes of starter dynamo problems:
- Worn carbon brushes
- Damaged starter solenoid
- Damaged or short-circuited dynamo coil
Solution
- Lightly tap the starter dynamo. Sometimes this method can help the dynamo continue to function for a while
- If the problem persists, take the car to a repair shop and ask to replace the dynamo.
Dirty or damaged spark plugs
The spark plugs in a car function to create the sparks needed for combustion in the engine room. If the spark plugs are dirty or damaged, this will inhibit the combustion process and the car will be difficult to start. Signs of a problematic spark plug:
- The car engine stutters or has no power
- The car is more wasteful of fuel
- A popping sound is heard from the exhaust
Solution
- If the spark plugs are worn out, which is indicated by not producing sparks, immediately replace them with new ones. Use spark plugs according to engine specifications to maintain optimal car performance
- Make sure the spark plug gap is according to factory specifications
Clogged fuel system
A clogged fuel system in a car will slow down the combustion process. A blockage in the fuel system causes the engine to not get enough fuel supply. Some of the main causes are:
- Dirty or clogged fuel filter
- Fuel pump is experiencing problems
- There is dirt or water in the fuel line
Solution
- If there are signs or there is water in the fuel tank, use a fuel additive that can absorb water. Or empty the fuel tank and refill with clean new fuel.
Broken fuse or electrical cable
Cars have a complex electrical system, and if one of the cables is broken or the fuse is burned, the power supply to the starter can be disrupted. Some common causes of electrical problems include:
- Broken main fuse.
- Loose or disconnected starter connecting cable.
- Faulty starter relay.
Solution
- Make sure the cable connecting the battery to the starter dynamo is not loose or peeled.
- If you are unsure about your car's electrical system, it is best to take it to a repair shop to be checked by a technician.
Conclusion
A car that won't start can be caused by various factors, ranging from a weak battery, problematic starter dynamo, damaged spark plugs, a clogged fuel system, to electrical problems. To keep your car in prime condition, do routine maintenance.
