Battery check:
* Check the battery terminals: Make sure the battery terminals are clean and secure.
* Check the battery voltage: Use a multimeter to check the battery voltage. It should be around 12.6V with the engine off and over 13V with the engine running.
* Check the battery capacity: Use a battery tester to check the battery capacity. It must meet the requirements of your vehicle.
Generator check:
* Check the charging system: Use a multimeter to check the alternator output voltage. It should be around 13.5-14.5 V with the engine running.
* Check the alternator belt: Make sure the alternator belt is tight and shows no signs of wear or damage.
Starter check:
* Check battery cables: Make sure all battery cables are securely attached and free of corrosion.
* Check Starter Solenoid: Use a test light to check if voltage is being applied to the starter solenoid when you turn the key.
* Check the starter itself: If the solenoid is OK, try starting the engine. If the starter does not turn or turns slowly, check it for signs of wear or damage.
Lighting check:
* Check the headlights: Turn on the headlights and make sure they are bright and properly adjusted.
*Check the brake lights: Press the brake pedal and make sure the brake lights are on.
* Check your turn signals: Turn on your turn signals and make sure they are flashing properly.
Checking fuses and relays:
* Check the fuses: Inspect the fuses and replace any blown ones.
* Test Relays: Use a relay tester to check if all relays are firing properly.
Other checks:
* Check Wiring: Inspect the wiring for damage, breaks, or signs of overheating.
*Check Grounding Points: Make sure all grounding points are clean and firmly grounded.
* Check electrical connectors: Check all electrical connectors for corrosion, damage, or loose connections.
