Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to ensure safety during work.

2. Battery Inspection and Testing

Tools Required: Multimeter, battery terminal cleaner, wrench set.
Check battery voltage using the multimeter. If it's below 12.6 volts, charge or replace the battery.
Clean the battery terminals with a battery terminal cleaner to remove any corrosion.
Ensure connections are tight and secure.

3. Starter and Ignition System Check

Tools Required: Socket set, multimeter, screwdriver.
Remove the starter motor by disconnecting its electrical connections and unbolting it from the engine.
Test the starter motor by connecting it directly to a fully charged battery. If it does not engage, replace the starter.
Check the ignition switch by accessing it and testing for continuity using a multimeter.

4. Fuse and Relay Inspection

Tools Required: Fuse puller or needle-nose pliers.
Locate the fuse box and check all fuses related to the starter and ignition system. Replace any blown fuses.
