1. Oxidized contacts and connections

Problem: Contacts and connectors can become oxidized due to moisture, causing poor connections and malfunctioning electrical components.

Prevention: Regularly inspect connectors and contacts, clean them if necessary, and treat them with a special anti-corrosion agent.

2. Overheated and damaged wiring

Problem: Wiring can overheat due to short circuits or improper installation, causing insulation to melt and possible fires.

Prevention: Regularly inspect wiring for damage and overheating, use fuses, and ensure that all electrical components are in good working order.

3. Grounding problems

Problem: Poor grounding can cause electronics to malfunction, such as headlights, alarms, or instrument clusters.

Prevention: Check grounding points for corrosion and tightness. Reinforce connections or replace damaged components if necessary.

4. Battery discharge

Problem: Constant battery discharge may be due to current leakage, short circuits or a faulty charging system.

Prevention: Regularly check the charging system, monitor the battery condition and eliminate current leaks as soon as possible.

5. Relay and fuse failure

Problem: Blown fuses or faulty relays can cause failure of the vehicle's electrical systems.

Prevention: Regularly check the condition of fuses and relays, replace them if necessary, and always use components with the correct ratings.

6. Sensor and electronic module failure

Problem: Faulty sensors can cause various systems such as ABS, engine management system and others to operate incorrectly.

Prevention: Diagnose and check the condition of sensors and electronic modules when suspicious symptoms or errors appear on the instrument panel.
