Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Battery Inspection

Sub-step 1: Remove the battery terminals (negative first, then positive).
Sub-step 2: Clean the terminals and battery posts using a wire brush to remove corrosion.
Sub-step 3: Reconnect the battery terminals (positive first, then negative).
Sub-step 4: Test the battery voltage again; replace the battery if it’s below 12.4 volts.

3. Starter Relay Check

Sub-step 1: Locate the fuse box and identify the starter relay.
Sub-step 2: Remove the starter relay and inspect for any visible damage.
Sub-step 3: Swap with a similar relay to test functionality.

4. Starter Motor Inspection

Sub-step 1: Locate the starter motor (usually near the transmission).
Sub-step 2: Test the voltage at the starter terminal with a multimeter while someone turns the ignition key.
Sub-step 3: If no voltage is detected, check the ignition switch and associated wiring.
Sub-step 4: If voltage is present but the starter does not engage, replace the starter motor.
