Disconnect the battery negative terminal to prevent electrical shorts.

2. Battery Inspection

Sub-steps:
1. Remove the battery cover if applicable.
2. Clean the battery terminals with a wire brush to remove any corrosion.
3. Reconnect the battery terminals securely.
4. Check the battery voltage again; if below 12.4 volts, proceed to replace the battery.

3. Starter Motor Testing

Sub-steps:
1. Locate the starter motor, typically near the engine block.
2. Disconnect the starter electrical connector.
3. Using a multimeter, check for voltage at the starter terminal while someone turns the key to the start position.
