    But I'm not blaming this one on wireless updates. I'm running an electric cooler, and my NOCO Genius 5 wasn't working, so I went out and bought a new one. Turns out it's a faulty connection in the fusebox. No continuity through the 10 mil lug it's attached to. I just need to clean it up and reconnect.

    I need to return the new one.

    UPDATE: It was a blown fuse. Why would they use a 4A fuse on a 5A charger? It has a 5 amp fuse now.
    I think I'll keep the new one; it was on sale, and it will be good to have a spare, which I'll probably need some day.

    Did you ever own a NOCO Genius 2 amp charger? Maybe you are using the wire harness from it with the NOCO Genius 5 amp charger.

    What you posted got me thinking about the three different size NOCO chargers that I own. So I took a look at them.
    The NOCO Genius 1 amp charger uses a 2 amp fuse in the wire harness.
    The NOCO Genius 2 amp charger uses a 4 amp fuse in the wire harness.
    The NOCO Genius 5 amp charger uses a 10 amp fuse in the wire harness.

    You may be right. I can't recall where the fuse was located. I did simply plug the new charger into the existing wiring. I had originally started with a NOCO Genius 2 and upgraded to a 5.

    UPDATE: You are correct. I just confirmed that the 4A fuse was in the part of the wiring harness that came with my Genius 2, which I left in place when I upgraded to the Genius 5. Nice catch.
