Solution

1. Preparation

• Gather necessary tools and parts for the repair.
• Disconnect the negative terminal of the battery for safety.

2. Battery Inspection and Testing

• Tools Required: Multimeter, wire brush, socket set
• Inspect the battery terminals for corrosion.
  • Clean terminals with a wire brush if corroded.
  • Ensure connections are tight and secure.
• Use the multimeter to check the battery voltage.
  • If below 12.4 volts, charge the battery or replace it if faulty.

3. Starter Motor Testing

• Tools Required: Jumper wires, multimeter
• Locate the starter motor.
• Use jumper wires to apply direct power to the starter motor.
  • If the starter engages and the engine cranks, the starter is functional; if not, replace the starter motor.

4. Fuse Inspection

• Tools Required: Fuse puller or pliers
• Locate the fuse box and check for any blown fuses related to the starter circuit.
  • Replace any blown fuses with the same amperage rating.

5. Ignition Switch Check

• Tools Required: Screwdriver, multimeter
• Remove the ignition switch assembly.
• Test for continuity using a multimeter to ensure the switch is functioning properly.
  • Replace if there is no continuity when the switch is in the 'start' position.

6. Wiring Inspection

• Tools Required: Multimeter
• Inspect the wiring harness connected to the starter and battery.
• Check for any visible damage, frays, or loose connections.
  • Repair or replace damaged wiring as necessary.
