Solution

1. Preparation

Gather tools: socket set, multimeter, jumper cables, and a wrench.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection

Sub-step 1: Disconnect the negative battery terminal using a wrench.
Sub-step 2: Clean the battery terminals and cable ends with a wire brush until shiny.
Sub-step 3: Reconnect the terminals securely, starting with the positive terminal followed by the negative.

3. Starter Motor Replacement (if defective)

Sub-step 1: Disconnect the negative battery terminal again for safety.
Sub-step 2: Remove any engine covers or components obstructing access to the starter motor.
Sub-step 3: Disconnect the wiring harness and the battery cable from the starter.
Sub-step 4: Unbolt the starter motor from its mounting bracket (typically 2-3 bolts) and remove it from the vehicle.
Sub-step 5: Install the new starter motor in reverse order, ensuring all connections are secure and bolts are torqued to specifications.

4. Testing the Starter Circuit

Sub-step 1: Reconnect the negative battery terminal.
Sub-step 2: Use a multimeter to check for voltage at the starter motor when the key is turned to the start position.
Sub-step 3: If voltage is present and the starter does not engage, replace the starter motor.
