    Gs550 1982 dyna S weak spark

    I just installed my dyna s in my 1982 GS550L and it does spark, but I'm not getting bright blue spark, I'm actually getting dim blue spark.

    The coils are getting hot, is that normal?

    What else can cause this?

    What is your Voltage to the coils?

      I just checked and it was under 10V, 8.5V to be exact so thats it.

      I just put the battery on the charger for the night.

        It is not a battery problem. Dirty connections between battery and coils.people normally do a coil relay mod.
