Solution

1. Preparation

Ensure the vehicle is in park (or neutral).
Disconnect the negative terminal of the battery to prevent electrical shock.
Gather necessary tools for the repair.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove any corrosion from the battery terminals using a wire brush.
2. Tighten the battery connections to ensure a solid connection.
3. If the multimeter reading is below 12.4 volts, consider replacing the battery.
4. Remove the battery by unscrewing the hold-down bracket and disconnecting the positive terminal first, followed by the negative terminal.
5. Install the new battery, connecting the positive terminal first, then the negative terminal.

Tools Required:

Wire brush
Wrench set
Multimeter

3. Starter Inspection and Replacement

Sub-steps:
1. Reconnect the battery and attempt to start the vehicle while observing the starter motor.
2. If the starter clicks but does not engage, remove it by disconnecting the wiring harness and unscrewing the mounting bolts.
3. Test the starter with a direct battery connection to see if it engages.
4. If faulty, replace the starter with a new unit.
5. Reinstall the new starter and reconnect all wiring securely.
