    Hey all, So i am trying to diagnose voltage loss. I have 12.5-12.8v at the battery. volts stay above 10v when i hit the start button. I am loosing voltage though on the wires going to the coils. One coil gets about 3 volts. the other is less than a volt. I did a resistance check on the kill switch and its fine. im getting 12v over to the eci. I did a ohms test on the voltage regulator and that seems good. Is it possible my ECI has gone out? or do you think im getting a voltage pull somewhere? pinched wire or corrosion?
    Thanks for any help here.

    ALso I am getting spark if the coils are on and also spark to the spark plugs. SO its enough to create spark but not enough for the bike to run. running is intermittent and only temporary. Maybe 30 secs and with starter fluid. I have also noticed if the bike starts running the gauge lights and headlight are delayed coming on.
