Solution

1. Preparation

Tools Required: Multimeter, battery tester, socket set, screwdriver, safety glasses, gloves.
Disconnect the negative battery terminal to ensure safety while working on the electrical system.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
- Clean any corrosion from the battery terminals using a wire brush.
- Ensure connections are tight and secure.
Test Battery Voltage:
- Reconnect the negative terminal.
- Use the multimeter to measure battery voltage; if below 12.4 volts, proceed to replace the battery.
Replace Battery (if necessary):
- Remove the positive terminal first, followed by the negative terminal.
- Unscrew any hold-down bracket securing the battery.
- Lift out the old battery and replace it with a new one, ensuring it is secured with the bracket.
- Reconnect the positive terminal first, then the negative terminal.

3. Starter Motor Inspection

Check Starter Connections:
- Locate the starter motor under the vehicle (usually near the transmission).
- Inspect wiring and connections for wear or damage; repair or replace as needed.
Test Starter Motor:
- Use a multimeter to check for voltage at the starter solenoid terminal while someone turns the key to the start position.
- If voltage is present but the starter does not engage, replace the starter motor.

4. Final Assembly

Recheck all connections and ensure everything is securely fastened.
Reconnect the negative battery terminal.
