Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is in a safe, flat location.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Sub-steps:
1. Clean battery terminals with a wire brush and apply terminal protector.
2. If the battery is weak (less than 12.4 volts), replace it with a new battery (12V, Group size 24F or 35).
Tools Required: Multimeter, wire brush, wrenches.
Safety Warnings: Always wear safety goggles and gloves when handling batteries.

3. Starter Motor Examination

Sub-steps:
1. Locate the starter motor (under the vehicle near the transmission).
2. Disconnect the power supply to the starter.
3. Remove the starter mounting bolts (usually 2-3) using a socket set.
4. Carefully pull the starter out and check for any visible damage.
5. Test the starter by applying direct power from the battery; if it doesn’t engage, replace it.
Tools Required: Socket set, wrench set.
Safety Warnings: Ensure the vehicle is securely lifted if using a jack.

4. Relay and Fuse Check

Sub-steps:
1. Access the fuse box under the dashboard or in the engine compartment.
2. Locate the starter relay and remove it.
3. Swap it with another similar relay to test functionality.
4. Replace any blown fuses found during inspection.
Tools Required: Fuse puller or needle-nose pliers.
Safety Warnings: Ensure the ignition is off before inspecting fuses.
