  • Wrench set

Repair Instructions:

  • If corrosion is found, clean the battery terminals with a terminal cleaner and reconnect.
  • If the battery voltage is low, recharge or replace the battery.
  • Identify the source of excessive parasitic draw using the multimeter, and inspect the related circuits or components (e.g., lights, radio, sensors) for faults.
