    And the lake test went just fine this afternoon. Yay!! Now I can get paid!

    Also to add some usefull info to the electrical on FUJI triples.
    With ignition coils hooked up in series backprobe the black and black with white stripe. While cranking you should read 200-300mV. If this drops below about 100mV, that's NOT enough output to fire a spark!
    Trigger coming from stator, that's the white with yellow stripe reading to ground. If cranking voltage drops below 1vac, it will NOT trigger a spark. Normal readings are1.5-3.5 vac.
    On the LR module....orange wire output at rest without cranking should be 0, no voltage. I have a shorted one here that reads several volts dc at rest. Normal while cranking is anything 8-12 vdc.

    I think you meant to say volts, not milli-volts (mV).

    So 200-300 volt pulses into the ignition coil series is normal/good, with 100 volt pulses being too weak to fire the spark plugs. Correct?

    You are talking about the black/white wire coming from the CDI to the first ignition coil, correct?
    With the other meter probe on engine ground (or CDI Black wire, or battery negative).

    Where is the main battery ground hooked up to?

My only guess is some sort of wierd electrical interference being transmitted through the ground system that the digital ignition does not like. Fingers crossed at this point and lake test as soon as the wind will quit blowing for a day!!!

    I'm guessing similar with beerdart.

    You will have continuity through the starter brushes to ground, from the positive starter cable. That red cable is and was still connected to your starter relay.

    The extra carbon dust from the brushes making unintended contact across additional segments of the starter armature ? Making it a stronger ground signal.

    Nope, I mean millivolts ac coming out of the cdi. Coils unhooked registers around 14vac.

    Main ground from the battery negative was originally on the motor plate, then tried the rear intake stud, finally reamed out the hole and put it on the right rear cylinder stud. None ever made a change, and all read only about .3 ohms resistance from battery negative to stator ground in ebox.

    Where exactly are you connecting your voltmeter probes?

    What meter settings? AC or DC?
