    The accessory could be a failure.

    First you must verify that power IS getting to the switch. IF so, then the connection to the switch, or switch itself may be faulty. IF not then you need to verify if power is getting to the fuse or breaker. If yes, then the problem is in the wiring between the fuse and the switch. There are no other possibilities.

    Source(s): logic and common sense.

    Bad ground or loose wire.

    Sure? Did you use a VOM and see? Just fuse being "in" and switch "on" means nothing.The link in those old 3AG glass fuses can come loose inside the cap and still "look" good. An ohmmeter will show open..

    Could be a myriad of things--depends on actual application. Could there be a lockout, safety? A limit switch? Bad connection, connector pulled out? Bad ground? Most electrical problems are simple, and you can see the problem if it's removed so you can examine it under good lighting, not stuffed inside a dash and guessing.

    Wiring open circuit or the thing plugged in is bad.

    I'd try a different fuse anyway.

      Need to verify Power with meter before trying anything else. Correct polarity, too. He does not indicate if this is a negative or positive ground car or What.
