1. Preparation

Gather tools and materials needed.
Tools Required: Multimeter, socket set, jumper cables, battery terminal cleaner, torque wrench, fuse puller.
Parts Required: New battery (if defective), new starter motor (if faulty), fuses (if blown).
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Battery Inspection and Replacement

Sub-steps:
1. Disconnect the negative terminal from the battery.
2. Clean battery terminals and cable connections using a battery terminal cleaner.
3. Reconnect the terminals securely.
4. If the battery is found defective, replace it with a new one:
  - Remove the battery hold-down bracket.
  - Lift the old battery out and install the new one.
  - Reconnect the positive terminal first, followed by the negative terminal.
  - Torque the terminal bolts to manufacturer specifications (typically 10-15 ft-lbs).

3. Starter Motor Testing and Replacement

Sub-steps:
1. If the battery is in good condition, locate the starter motor (usually near the engine transmission interface).
2. Disconnect the electrical connector and the battery cables from the starter.
3. Remove the starter mounting bolts using a socket set.
