Solution

1. Preparation

Ensure the vehicle is off and parked safely.
Gather the following tools: multimeter, safety gloves, and safety goggles.

2. Connect the Multimeter

Positive Lead: Connect the red lead of the multimeter to the positive terminal of the battery (marked with a "+" symbol).
Negative Lead: Connect the black lead of the multimeter to the negative terminal of the battery (marked with a "-" symbol).

3. Read the Voltage

Check Voltage: Observe the reading on the multimeter. A fully charged battery should display around 12.6 volts or higher. A reading below 12.4 volts indicates the battery is partially discharged, while below 12.0 volts suggests it may need charging or replacement.

4. Disconnect Multimeter

Remove the leads from the battery terminals in reverse order (black lead first, then red lead) to avoid any short circuits.
