Solution

1. Preparation

Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery terminal to prevent electrical shorts.
Gather tools: multimeter, wrench set, jumper cables, or battery charger.

2. Battery Inspection and Replacement

Check Battery Condition:
- Use a multimeter to measure voltage.
- If below 12.4 volts, proceed to charge or replace the battery.
Cleaning Terminals:
- Remove battery terminals using a wrench.
- Clean the terminals and cable connectors with a wire brush and baking soda solution.
- Dry thoroughly before reattaching.
Replace Battery (if necessary):
- Remove the old battery and install a new one, ensuring correct polarity.
- Tighten terminals securely.

3. Starter Inspection and Replacement

Testing Starter:
- If the battery is good, check connections at the starter.
- Use a multimeter to check for voltage at the starter while someone turns the key.
Replace Starter (if necessary):
- Remove the starter by disconnecting the battery and unbolting it from the mounting.
- Install the new starter and reconnect all wiring securely.
- Reattach battery terminals.
