Battery Replacement (if needed):
- Remove the battery hold-down clamp using a socket set.
- Disconnect the positive terminal first, followed by the negative terminal.
- Remove the old battery and replace it with a new one, ensuring it matches the specifications.
- Reconnect terminals: positive first, then negative.
Alternator Check (if needed):
- Remove the serpentine belt using a socket and ratchet.
- Unplug the alternator connector and remove the mounting bolts.
- Replace the alternator with a new one, ensuring all connections are secure.
Fuse Replacement (if needed):
- Locate the fuse box and identify any blown fuses related to the charging system.
- Replace any blown fuses with the appropriate amperage fuses.
