Solution

1. Preparation

Gather necessary tools: multimeter, socket set, wrench set, and safety gloves.
Ensure the vehicle is in park or neutral and the parking brake is engaged.

2. Battery Inspection

Sub-step 1: Disconnect the negative terminal of the battery to prevent electrical shorts.
Sub-step 2: Inspect the battery terminals for corrosion; clean with a wire brush if necessary.
Sub-step 3: Reconnect the terminals and ensure they are tight. Test the battery voltage again.

3. Starter Motor Testing

Sub-step 1: Locate the starter motor, usually found near the transmission.
Sub-step 2: Use a multimeter to check if power is reaching the starter motor when the ignition is turned on.
Sub-step 3: If no power is present, check the starter relay and ignition switch.

4. Replace Battery or Starter (if necessary)

Sub-step 1: If the battery voltage is low or the battery fails the load test, replace it with a new, fully charged battery of the correct specifications.
Sub-step 2: If the starter motor is determined to be faulty, remove it by unbolting from the engine and disconnecting wires, then replace it with a new starter motor.
