Solution

1. Preparation

Gather tools and parts.
Safety gear: gloves and goggles.
Disconnect the negative terminal of the battery.

2. Battery Inspection

Remove the battery terminals (negative first, then positive).
Clean any corrosion from the terminals and cable ends using a wire brush.
Reattach the battery terminals securely.

3. Battery Voltage Test

Connect the multimeter leads (red to positive, black to negative).
Check the voltage reading; it should be at least 12.6 volts for a fully charged battery.
If the voltage is low, charge or replace the battery.

4. Starter Motor Test

Locate the starter motor (usually near the transmission).
Disconnect the electrical connector from the starter motor.
Use a jumper wire to connect the positive terminal of the battery directly to the starter motor terminal.
Listen for a clicking sound or the starter engaging. If it clicks but does not turn, replace the starter.

5. Ignition Switch Inspection

Remove the steering column cover to access the ignition switch.
Check the wiring harness for damage or loose connections.
Test the ignition switch with a multimeter to ensure it is functioning properly.

6. Fuse Check

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove and inspect fuses related to the starting system.
Replace any blown fuses with a fuse of the same rating.
