Solution

1. Preparation

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

2. Battery Inspection and Replacement

Check Battery Voltage:
- Use a multimeter to measure the voltage. If it’s below 12.4 volts, proceed to charge or replace the battery.
- If the battery is weak, connect a battery charger and charge it fully.
Clean Battery Terminals:
- Remove the battery terminals using a socket set.
- Clean the terminals and cable ends with a wire brush and a battery terminal cleaner.
- Reattach the terminals securely.

3. Starter Motor Inspection

Locate the Starter Motor:
- Refer to the vehicle manual to locate the starter motor.
Bypass the Starter:
- Using jumper wires, connect the positive terminal of the battery directly to the starter motor terminal and the negative to the motor housing.
- If the starter engages and the engine cranks, the starter is faulty and needs replacement.
Remove and Replace Starter:
- Disconnect the wiring harness from the starter.
- Remove the mounting bolts using a socket set.
- Replace with a new starter, ensuring it is aligned correctly and securely fastened.

4. Final Checks

Reconnect Battery:
- Reconnect the negative battery terminal after all repairs are complete.
Test Start the Vehicle:
- Attempt to start the vehicle to check if the issue is resolved.
