Solution

1. Preparation

Gather tools: multimeter, battery terminal cleaner, socket set, load tester, and a wrench.
Ensure the vehicle is in park (or neutral) and the emergency brake is engaged.

2. Battery Inspection and Replacement

Step 1: Disconnect the negative battery terminal first, followed by the positive terminal to avoid short circuits.
Step 2: Clean both terminals and cable ends with a battery terminal cleaner to remove corrosion.
Step 3: Reconnect the positive terminal first, then the negative terminal.
Step 4: If the battery is faulty, remove it using a socket set and replace it with a new battery of the same specifications (usually a 12V lead-acid or lithium battery).
Step 5: Ensure the battery is securely fastened and connections are tight.

3. Starter Motor Inspection

Step 1: Locate the starter motor (typically near the transmission).
Step 2: Inspect the wiring and connections to the starter; repair or replace any damaged wires.
Step 3: If necessary, remove the starter motor using a socket set and test it separately on a workbench with a jump battery.
Step 4: If the starter is defective, replace it with a new one of the same type.
