Solution

1. Preparation

• Tools Required: Multimeter, socket set, jump starter, battery terminal cleaner.
• Disconnect the negative terminal of the battery before performing any electrical checks.
• Ensure the vehicle is in park (automatic) or neutral (manual) for safety.

2. Battery Inspection

• Sub-steps:
  1. Use a multimeter to measure the battery voltage. If it is below 12.4 volts, proceed to charging or replacing the battery.
  2. Clean any corrosion from the battery terminals using a battery terminal cleaner.
  3. Tighten any loose connections at the battery terminals.

3. Starter Relay and Fuses Check

• Sub-steps:
  1. Locate the fuse box and identify the starter relay.
  2. Remove the starter relay and swap it with a similar one to test functionality.
  3. Inspect the fuse associated with the starting system. Replace any blown fuses with the correct amperage.

4. Wiring Inspection

• Sub-steps:
  1. Trace the wiring from the battery to the starter motor.
  2. Look for any signs of physical damage, fraying, or disconnections.
  3. Repair or replace damaged wiring as necessary.

5. Starter Motor Testing

• Sub-steps:
  1. If the above steps do not resolve the issue, remove the starter motor for testing.
  2. Bench test the starter motor by connecting it directly to a charged battery.
  3. If the starter does not engage or spin, replace the starter motor.
