Solution

1. Preparation

Tools Required: Multimeter, socket set, jumper cables, wrench set.
Disconnect the battery by removing the negative terminal first to ensure safety.

2. Battery Inspection

Sub-steps:
1. Clean any corrosion from battery terminals using a wire brush.
2. Ensure battery connections are tight and secure.
3. If the battery voltage is low, recharge or replace the battery.

3. Jump-starting the Vehicle

Sub-steps:
1. Connect jumper cables: red to the positive terminal of the dead battery and the working battery, black to the negative terminal of the working battery, and then to a ground on the dead vehicle.
2. Start the working vehicle for a few minutes before attempting to start the Mustang.

4. Starter Motor and Solenoid Check

Sub-steps:
1. Locate the starter motor under the vehicle.
2. Disconnect the wiring harness from the starter motor.
3. Use a multimeter to test for voltage at the starter terminal while turning the ignition; if no voltage is present, the solenoid may be faulty.
4. If voltage is present but the starter does not engage, replace the starter motor.

5. Fuses and Ignition Switch

Sub-steps:
1. Locate the fuse box and check for any blown fuses related to the starting system (consult the owner’s manual for fuse locations).
2. Replace any blown fuses with the correct amperage.
3. Test the ignition switch by checking for continuity when turned to the "start" position; replace if faulty.
