    i have a 2012 Heritage Softail Classic and am having electrical issues. I will b riding down the road and the speedometer will lose power (lights go off), and at the same time the auxiliary lights in the front and back will go off but only for a few seconds then they all come back on. I never lose the main headlight or the main taillight but the others go off. when i checked the error codes this is what i am getting and also what i believe to be the definition of each error code:
    ECM: y
    p0562-battery/ecm voltage low
    pn001118-01

    BCM: y
    b2121-starter output open
    b2272-bcm/im voltage high
    pn69991-11a

    SPDO: y
    b2272-bcm/im voltage high
    pn70900171

    i am guessing that the pn number is the part number of the origin of the error code(?). any ideas what would cause the loss of power and the flickering of the lights?

    First thing that comes to mind ,is connections on batterie!. If these are loose ,or corroded ,or both this can happen.
    So check this ,erase the codes, and go for a testdrive. If codes don't re-appear , I suppose everything is OK.

    +1 on above, check the simple things first especially if everything seemed fine before.

    If Your battery is 8 years old,it's time for replacement.All kinds of weird symptoms can appear with a weak battery.
