Diagnostic Steps

1
Check the battery voltage using a multimeter.
2
Inspect battery terminals and connections for corrosion or looseness.
3
Test the starter motor for functionality.

Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, and cleaning materials.
Ensure the vehicle is in 'Park' and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Testing

Remove the battery terminals (negative first, then positive).
Clean any corrosion from the terminals using a wire brush and a mixture of baking soda and water.
Reconnect the battery terminals (positive first, then negative).
Use the multimeter to measure voltage. It should read around 12.6 volts for a fully charged battery. Anything below 12.4 volts indicates a weak battery.
If the battery is weak, proceed to replace it with a new one.

3. Starter Motor Inspection

Locate the starter motor (usually near the engine block).
Disconnect the wiring harness from the starter motor.
Use a multimeter to check for voltage at the starter terminal while turning the key to the 'start' position.
If there is no voltage, check the ignition switch and associated wiring.
If voltage is present, test the starter motor by connecting it directly to the battery (ensure safety precautions).

4. Ground and Connections Check

Inspect the ground connections from the battery to the chassis and the engine.
Clean and tighten any loose or corroded connections.
Ensure all connections are secure before attempting to start the vehicle again.
