🔧 Reasons for salt formation on car battery poles

Salts are formed on the poles due to the reaction between hydrogen gas emitted from the battery during repeated charging and discharging operations. Hydrogen gas reacts with the copper, aluminum or lead from which the poles are made, and salt deposits are formed.

These deposits are an indication that the car's electrical system is not in good condition. If the deposit is on the negative pole, this means that the battery is less charged than required. If it is on the positive pole, this means that the battery is more charged than required.

If it is on both poles and occurs after long periods (six months, for example), this is normal and is related to the humidity of the atmosphere. However, if it occurs repeatedly in short periods, this is evidence that the electrical connections may be weak or not well fixed.

🔧 The solution in three steps:

1. Clean the deposits:
- Using a toothbrush and soap, if available.
- Using a plastic brush and hot water.
- Using soft drinks, it is very effective in removing carbon deposits.

2. Ensure the safety of the electrical system:
- Measure the charging generator (dynamo generator) and the battery.
- It is preferable to do this in a specialized workshop.

3. Safety precautions:
- Wear gloves when handling the battery.
- Wear protective glasses.
- Avoid touching your clothes to the battery, as it will damage it.

Spark Plug Problems: Causes and Symptoms

Spark plugs are crucial components in your car's engine, responsible for igniting the air-fuel mixture. When they malfunction, it can lead to various engine problems.

Common Spark Plug Issues
1. Fouled Spark Plugs:
- Description: Spark plugs become covered in carbon, oil, or other deposits, preventing a strong spark.
- Causes: Rich fuel mixture, low engine RPM, excessive idling, worn engine components, or incorrect spark plug heat range.
- Symptoms: Rough idle, poor acceleration, decreased fuel economy, engine misfires.

2. Worn Spark Plugs:
- Description: Electrodes become eroded or damaged over time, reducing spark efficiency.
- Causes: Normal wear and tear, improper gap, or overheating.
- Symptoms: Similar to fouled plugs, but often accompanied by misfires under load.

3. Incorrect Spark Plug Gap:
- Description: The gap between the spark plug electrodes is not within the specified range.
- Causes: Improper installation or wear.
- Symptoms: Misfires, difficulty starting, rough idle, decreased performance.

4. Overheated Spark Plugs:
- Description: Spark plugs become excessively hot, leading to premature wear and damage.
- Causes: Incorrect heat range, lean fuel mixture, pre-ignition, or detonation.
- Symptoms: Pre-ignition, engine knocking, reduced performance, and potential engine damage.

5. Damaged Spark Plugs:
- Description: Physical damage to the spark plug, such as cracked insulators or broken electrodes.
- Causes: Foreign objects, overheating, improper installation, or engine misfires.
- Symptoms: Misfires, engine roughness, and potential engine damage.

Symptoms of Bad Spark Plugs
- Rough idle: Engine shakes or vibrates when idling.
- Difficulty starting: Engine cranks but doesn't start easily.
- Misfires: Engine skips or hesitates during acceleration or under load.
- Decreased fuel economy: Vehicle gets fewer miles per gallo
