Solution

1. Preparation

Tools Required: Multimeter, socket set, jumper wire, battery terminal cleaner, wrenches
Disconnect the negative battery terminal to ensure safety during repairs.

2. Battery Inspection

Sub-steps:
1. Clean battery terminals and cable connectors using a battery terminal cleaner.
2. Reconnect the battery and check for tightness.
3. If the battery voltage is low, recharge the battery or replace it if necessary.

3. Starter Motor Test

Sub-steps:
1. Locate the starter motor on the engine.
2. Use a jumper wire to connect the positive terminal of the battery directly to the starter motor terminal.
3. If the motor engages and the engine turns over, the starter is functioning but may have an issue with the ignition circuit.

4. Replace Starter Relay (if necessary)

Sub-steps:
1. Locate the starter relay in the relay box (refer to the owner’s manual for exact location).
2. Remove the relay using a socket or pliers.
