Solution

1. Preparation

Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery terminal using a socket wrench to prevent electrical shock.

2. Battery Testing and Replacement

Sub-step 1: Clean battery terminals with a wire brush if corrosion is present.
Sub-step 2: Reconnect the battery and test voltage again; if below 12.4 volts, replace the battery.
Sub-step 3: Remove the old battery by disconnecting positive terminal first, then negative. Lift out the battery carefully.

3. Starter Testing and Replacement

Sub-step 1: Locate the starter motor, typically found near the engine block, secured with bolts.
Sub-step 2: Disconnect the wiring harness from the starter by pressing the clip and pulling it off.
Sub-step 3: Remove the starter mounting bolts using a socket set and lift the starter out.
Sub-step 4: Install the new starter by reversing the removal steps. Tighten bolts to manufacturer specifications.
Sub-step 5: Reconnect the wiring harness to the new starter.
