Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on the electrical system.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
- Clean any corrosion using a wire brush and a mixture of baking soda and water.
- Tighten loose connections securely.
Test and Replace Battery if Necessary:
- If the battery voltage is below 12.4 volts or fails the load test, replace the battery.
- Ensure the new battery is fully charged before installation.

3. Starter Motor Inspection

Check Starter Connections:
- Remove the starter motor's electrical connections and inspect for corrosion.
- Clean the terminals and reconnect them tightly.
Test Starter Motor Functionality:
- If the connections are good but the issue persists, remove the starter motor.
- Bench test the starter motor using jumper cables to check if it engages.
Replace Starter Motor if Faulty:
- If the starter does not engage during the bench test, replace with a new starter motor.

4. Fuse and Relay Check

Inspect Fuses:
- Locate the fuse box and check for any blown fuses related to the starter circuit.
- Replace any blown fuses with the correct amperage rating.
Check Starter Relay:
- Swap the starter relay with another identical relay in the fuse box to test functionality.
