Solution

1. Preparation

Tools Required: Wrench set, multimeter, jump wires
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection

Sub-steps:
1. Reconnect the battery and check voltage with a multimeter.
2. If voltage is low, remove the battery and charge it or replace it if necessary.
3. Clean battery terminals with a wire brush and reconnect securely.

3. Starter Motor Test

Sub-steps:
1. Locate the starter motor (usually near the engine's transmission).
2. Use jump wires to connect the starter motor directly to the battery.
3. If the starter engages, it may indicate a faulty ignition switch or relay.
4. If it does not engage, replace the starter motor.

4. Wiring and Fuse Check
