    Radio Interference

    Lookin' fer a solution

    '96 Road King w/Road Teck (harley accessory) radio - AM/FM/WB & Auxillary input (i.e. from an ipod).

    Situtation:  interference on the radio / aux input when the bike is running, especially once the RPMs start to get to highway speed.  Sound is perfect when the bike is sitting stil with the engine off.

    Decades ago, there used to be some kind of a filter you could get for the antena or wiring (can't remember which) - anybody have any ideas?  Know of any specific parts?


    The first tool out of the box should be the "book"  Geeked

    Re: Radio Interference

    Yeah, I remember those filters too Keith, but forgot exactly what they were. Try grounding the antenna. Make sure the spark plugs and wires are resistor type. You could also try shielded plug wires (braided), and hooking the radio ground directly to the battery...If I think of anything else I'll let ya know...

    If ya got any old Chevy HEI distributor parts lay'n around, ya might try the resistor that goes in there. Hook it in parallel with the hot line of the radio. The part we were thinking about from the olden days was maybe a MOPAR external ignition resistor, from the 60's 70's...Yeah right, try explaining that to these kids at the auto parts store...

    I think they make an automotive radio static resistor. Do some Googling Keith...



    Don't force it, get a bigger hammer.
