Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface with the parking brake engaged.
Tools Required: Multimeter, socket set, screwdriver, battery terminal cleaner.

2. Battery Terminal Cleaning

Disconnect the negative battery cable first, followed by the positive cable.
Use a battery terminal cleaner to remove any corrosion from the terminals and connectors.
Reconnect the positive cable first, then the negative cable securely.

3. Battery Replacement (if necessary)

If the battery voltage is below 12.4 volts, replace the battery.
Remove the battery hold-down bracket using a socket set.
Carefully lift the battery out and replace it with a new, fully charged battery.
Reconnect the terminals (positive first, then negative) ensuring they are tight.

4. Starter Motor Inspection

If the battery is good, locate the starter motor.
Remove the electrical connections to the starter motor, noting their positions.
Test the starter motor by directly connecting it to a known good battery.
If the starter does not engage, it needs to be replaced.
If it engages, check the wiring and connections from the ignition switch to the starter.
