  1. Disconnect the connector and remove the the PCB block (A).

Fuse

  1. Be sure there is no play in the fuse holders, and that the fuses are held securely.
  2. Are the fuse capacities for each circuit correct?
  3. Are there any blown fuses?
  • If a fuse is to be replaced, be sure to use a new fuse of the same capacity. Always determine why the fuse blew first and completely eliminate the problem before installing a new fuse.

Multi Fuse
