Solution

1. Preparation

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

2. Battery Inspection

Tools Required: Multimeter, wire brush, wrench
Inspect the battery for corrosion:
- Clean the terminals with a wire brush if corrosion is present.
- Tighten any loose connections.
Test battery voltage:
- Connect the multimeter to the battery terminals and check the voltage.

3. Starter Relay Check

Tools Required: Flathead screwdriver
Locate the starter relay in the fuse box:
- Remove the relay and inspect for damage.
- Replace it with a similar relay from the fuse box to test functionality.

4. Fuses Inspection

Tools Required: Fuse puller or pliers
Check the relevant fuses:
- Remove each fuse related to the starting system and inspect for continuity.
- Replace any blown fuses with the correct amperage fuse.

5. Starter Circuit Voltage Drop Test

Tools Required: Multimeter
Perform a voltage drop test:
- Connect the multimeter leads to the positive terminal of the battery and the starter terminal.
- Have an assistant turn the key to the start position and observe the voltage reading; it should be minimal.
- If the voltage drop is significant, check wiring and connections for damage.

6. Finalizing

Reconnect the battery terminal securely.
Ensure all components are reinstalled correctly.
