Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe, well-ventilated area.
Disconnect the negative battery terminal using a wrench to prevent electrical shock.

2. Inspect Battery Connections

Reconnect the positive terminal first, then the negative terminal.
Ensure terminals are clean; use a wire brush if necessary.
Tighten terminals securely without over-torquing.

3. Test and Replace Fuses

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Use a fuse puller or pliers to remove any suspect fuses.
Inspect fuses visually or use a multimeter to check continuity; replace any blown fuses with ones of the same amperage.

4. Check Starter Motor

Identify the starter motor's location (typically near the engine block).
Remove the electrical connector from the starter.
Use a jumper wire to connect the positive terminal of the battery directly to the starter terminal; listen for a clicking sound indicating the starter is attempting to engage.
If there is no response, replace the starter motor.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Turn the ignition key to the 'ON' position and check the dashboard for any warning lights.
Try to start the vehicle and observe any changes in symptoms.
