    I ordered this battery harness for a 2018 Road King. I was having issues with the original factory harness. This harness was easy to install. It's working as intended. Shipping was quick.

    Excellent to have no need to take seats off to trickle charge a battery anymore. Light indicates when it needs to be charged.

    I had already bought similar models, but they weren't as robust as this one.

    Can I run the Harley heated jacket off the LED indicator battery charging harness 66000005 ?
    Sarge - SE USA
    • Answer:
      The inline fuse is 7.5 if the draw is less it should work, rewiring might be necessary.
      • Answer:
        Hi Sarge, This item is for use with Harley-Davidson® 12-volt batteries. Thank you

    I replaced my old charging harness with this new led indicator charging harness . I was able to charge my phone or connect my air pump with the one harness but I don’t have power when I connect my phone or air pump to this led indicator charging harness

    is there a right or wrong way to attach the pigtail to the battery?

    • Answer:
      DUH! If you don't know the answer to that... Red is Positive/Black is Negative, just like your battery.

      • Answer:
        corby06ultra; There is a correct and incorrect way to install this pigtail harness to your battery. The lead that has the fuse holder will go to your positive battery terminal, the other black lead will go to your negative battery terminal. You can find the Isheet on Harley-Davidson website, search the PN and Isheet is available under details. Thanks, LeakyShovel73 read more.

    Will the LED indicator still function properly with other then running directly off the battery? I’m guess no as I have these on both my bike and they worked as advertised until extra things were run to the battery. Now neither one will flash.
    craigffb1 - Clarksville TN
    • Answer:
      Hello craigffb1, When this LED Indicator Battery Charging Harness is not properly connected, it may act as you have described. The LED indicator light will flash red when the battery needs charging. Regularly monitor the status of the indicator light. If battery voltage falls below 3V, the indicator light may no longer flash. Thank you, Captain Slow read more.
