Solution

1. Preparation

Tools Required: Socket set, multimeter, battery terminal cleaner, load tester.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection and Replacement

Check Battery Condition:
- Clean the battery terminals using a terminal cleaner.
- Reconnect the battery terminals securely.
- If battery voltage is low or the battery fails the load test, replace the battery.
Installation:
- Remove the old battery by loosening the terminal clamps (negative first, then positive).
- Place the new battery in the battery tray and secure it with the hold-down bracket.
- Connect the positive terminal first, followed by the negative terminal.

3. Starter Motor Inspection

Access Starter Motor:
- Raise the vehicle safely on jack stands.
- Remove any undercovers or shields to gain access to the starter motor.
Inspect and Test:
- Check the starter motor connections for tightness and corrosion.
- Use a multimeter to test for voltage at the starter terminal when the ignition is turned on.
- If no voltage is present, trace wiring back to the ignition switch.
Replace Starter Motor if Necessary:
- If the starter is faulty, remove the mounting bolts and disconnect the wiring.
- Install the new starter by reversing the removal steps and torque bolts to manufacturer specifications.
