Diagnosis of electrical fault
1. Inspect fuses and relays: Check for blown fuses or failed relays. Replace any faulty components.
2. Battery test: Measure the voltage on the battery using a voltmeter. It should be between 12.6-13.2 volts. If the voltage is too low, charge or replace the battery.
3. Checking the generator: Start the engine and measure the voltage at the generator. It should be between 13.8-14.4 volts. If the voltage is too low, the alternator may be faulty or the drive belt may be slipping.
4. Wiring Inspection: Inspect the wiring for damage such as chafing, breaks, or oxidation. Replace or repair any faulty wires.
Electrical fault repair
1. Replacing fuses and relays: Find the faulty fuse or relay and replace it with a new one of the same capacity and type.
2. Charging or replacing the battery: Charge the battery or replace it if it is faulty.
3. Repair or replace the generator: If the generator is faulty, repair it or replace it with a new one.
4. Repair or replace wiring: Repair or replace faulty wiring, ensuring a reliable and insulated connection.
5. Repair current leakage: If current leakage is detected, trace the current source and repair any faulty components or connections.
Precautions
