Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection and Replacement

Inspect the Battery:
- Remove battery terminals (negative first, then positive).
- Clean terminals and cable ends with a wire brush.
- Test the battery with a multimeter; replace if voltage is below 12.4 volts.
Replace Battery (if necessary):
- Remove the old battery and dispose of it properly.
- Install the new battery, connecting positive terminal first, followed by negative.
- Ensure terminals are tight and free of corrosion.

3. Starter Motor Inspection

Check Starter Connections:
- Locate the starter motor under the vehicle.
- Inspect electrical connections at the starter for corrosion or looseness.
Test Starter Function:
- Use a jumper wire to bypass the ignition switch and directly power the starter.
- If the starter engages, it may indicate an issue with the ignition switch or relay.

4. Ignition Switch and Relay Replacement

Locate the Ignition Relay:
- Remove the relay from the fuse box (consult the owner’s manual for location).
Replace the Ignition Relay:
- Install a new relay in the same position.
- Reassemble any components removed for access.
