\n

5<\/p>\n<\/td>\n

\n VERIFY AUDIO AMPLIFIER POWER SUPPLY VOLTAGE<\/b><\/p>\n\n

Yes<\/p>\n<\/td>\n

\n

Go to the next step.<\/p>\n<\/td>\n<\/tr>\n

\n

No<\/p>\n<\/td>\n

\n

Inspect the AUDIO1 25 A fuse, CABIN+B 50 A fuse, and MAIN 200 A fuse.<\/p>\n

    \n
  • \n

    Any fuse is blown:<\/p>\n<\/li>\n

      \n
    • \n

      Refer to the wiring diagram and verify if there is a common connector between MAIN 200 A fuse and audio amplifier 3A.<\/p>\n<\/li>\n

        \n If there is a common connector:<\/b><\/p>\n
      • \n

        Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for short to ground to determine the malfunctioning location.<\/p>\n<\/li>\n

      • \n

        Repair or replace the malfunctioning location.<\/p>\n<\/li>\n<\/ul>\n
