Solution

1. Preparation

Gather tools: multimeter, socket set, load tester, and wrenches.
Ensure the vehicle is in park (automatic) or neutral (manual) with the parking brake engaged.
Disconnect the negative terminal of the battery to ensure safety.

2. Battery Inspection and Replacement

Inspect Battery:
- Remove the battery terminal covers.
- Check for any visible corrosion or leaks.
Test Battery:
- Reconnect the battery and use a multimeter to check voltage.
- If the voltage is below 12.4 volts, charge the battery or replace it if it doesn’t hold a charge.
Replace Battery (if necessary):
- Disconnect the negative terminal first, then the positive terminal.
- Remove the battery hold-down bracket.
- Lift the old battery out and install the new battery in reverse order, ensuring terminals are tightened securely.

3. Starter Motor Inspection and Testing

Inspect Starter Connections:
- Locate the starter motor and check wiring connections.
- Ensure all connections are tight and free of corrosion.
Test Starter Operation:
- With the battery reconnected, use a multimeter to check for voltage at the starter terminal while attempting to start the engine.
- If no voltage is present, the ignition switch or wiring may be faulty.
Replace Starter (if necessary):
- Disconnect the battery again.
- Remove the starter motor by unbolting it from the mounting location.
- Disconnect wiring harness from the starter before removing it completely.
- Install the new starter by reversing the removal steps, ensuring all connections are secured.
