Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery by removing the negative terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Check Battery Condition
1. Use a multimeter to measure battery voltage. If below 12.4 volts, proceed with charging or replacing.
2. Clean battery terminals with a wire brush if corrosion is present.
Replace Battery (if necessary)
1. Remove the battery hold-down bracket using a socket set.
2. Carefully lift out the old battery and replace it with a new one, ensuring correct orientation.
3. Reattach the hold-down bracket and connect the positive (+) terminal first, followed by the negative (-) terminal.

3. Starter Inspection and Replacement

Check Starter Motor
1. Locate the starter motor beneath the vehicle, usually near the transmission.
2. Inspect for any visible damage or connections that are loose.
Replace Starter Motor (if necessary)
1. Disconnect the wiring harness and the battery terminals from the starter.
2. Remove the starter mounting bolts using a socket set.
3. Carefully remove the starter motor from its housing and replace it with a new starter.
4. Reinstall the mounting bolts and reconnect the wiring harness.
