Solution

1. Preparation

Gather necessary tools and parts for the repair.
Disconnect the negative battery terminal to ensure safety during the repair process.

2. Inspect and Clean Battery Terminals

Sub-steps:
1. Remove the positive and negative battery cables from the battery terminals.
2. Clean the terminals and cable ends with a wire brush to remove any corrosion.
3. Reconnect the battery cables, starting with the positive terminal followed by the negative terminal.
Tools Required: Wire brush, socket set.

3. Test/Replace the Battery

Sub-steps:
1. If the battery voltage is below 12.4 volts, charge the battery using a battery charger.
2. If the battery cannot hold a charge, replace it with a new one of the same specifications.
Tools Required: Battery charger (if charging), socket set (for battery removal).

4. Inspect Starter Motor

Sub-steps:
1. Locate the starter motor under the vehicle.
2. Disconnect the wiring harness from the starter.
3. Use jumper cables to connect the starter directly to the battery to check for functionality.
4. If the starter engages, it is functioning properly. If not, it should be replaced.
Tools Required: Socket set, jumper cables.

5. Check Voltage Drop

Sub-steps:
1. Reconnect the negative battery terminal.
2. Use a multimeter to measure voltage at the starter motor while someone attempts to start the vehicle.
3. If the voltage drop exceeds 0.5 volts, inspect and possibly replace the battery cables.
Tools Required: Multimeter.
