Solution

1. Preparation

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

2. Battery Inspection and Replacement

Sub-steps:
1. Inspect battery terminals for corrosion. Clean terminals using a wire brush and a mixture of baking soda and water if necessary.
2. If the battery voltage is below 12.4 volts, charge the battery using a battery charger.
3. If the battery is defective (as indicated by the load tester), replace it with a new, compatible battery.
Tools Required: Wire brush, battery charger, wrench set.
Safety Warnings: Always wear gloves and safety goggles while handling batteries.

3. Starter Motor Inspection

Sub-steps:
1. Reconnect the negative battery terminal after battery checks.
2. Locate the starter motor (usually near the transmission).
3. Inspect the electrical connections to the starter motor; tighten any loose connections.
4. If the connections are intact, tap the starter lightly with a hammer to see if it engages.
5. If the starter does not engage, remove it and test it separately or replace it if faulty.
Tools Required: Socket set, hammer.
Safety Warnings: Ensure the vehicle is in park or neutral with the parking brake engaged.
