2. Tighten the terminal connections to ensure a secure fit.
3. If battery voltage is low, jump-start the vehicle or replace the battery if it is old or faulty.

Tools Required:

Multimeter
Wire brush
Wrench set

3. Starter Inspection

Sub-steps:
1. Locate the starter motor (typically located near the engine's transmission).
2. Remove the electrical connector from the starter.
3. Use a jumper wire to connect the positive terminal of the battery to the starter solenoid terminal.
4. If the starter engages and the engine cranks, the starter is faulty and needs replacement.
