    New coil and still no spark. I misspoke on what I’m getting voltage wise to the black/white coil wires. It’s more like 40v. Weird thing is, I can hook up one of those incandescent inline spark testers and it will blink as if it was firing each revolution. But put a plug and test for spark and nothing.

    I tested both magneto coils for voltage output. I got 4v out of the exciter and charging coils while cranking. Ohm tests still pass. Is that output from magneto low? I can’t find any specs on output voltage during cranking. Something is causing the cdi to send weak voltage to the spark plug coil causing it to not have enough energy to spark the plugs.

    How exactly were you testing for spark with a loose spark plug?

    The single coil wasted spark design used on the two cylinder ignition coil requires that both spark plug wires be connected to spark plugs and both of those spark plugs be in contact with the cylinder heads. If either spark plug wire is just hanging in the air the other spark plug will not be able to fire properly, even if it is touching the cylinder head.

    One boot secured on the holder. Other boot with plug holding it to the tip of other boot holder. As mentioned, I get “energy” traveling through using the inline tester. But no spark from plugs. Which are new btw.

    I think your ac voltage from the stator is low. I'll check my specs tomorrow but I'm thinking 40-50 vac from the excitor and 20vac from charge.

    Would you be willing to create a new post in the Tech or FAQ sections with whatever info you have regarding carb engine stator coil cranking and running AC voltages.

    IIRC this info is absent from the Polaris service manuals and I am unsure whether it has ever been posted in a concise manner in one place.

    Found this thread that both of you contributed to. Myself, you posted cranking specs for gen I red engine voltages. I would be shocked if the gen III was much different in terms of voltages supplied from the exciter and charge coils.

    2000 Virage 2 Cylinder - No Spark

    Battery cranking voltage @10.96v
    Excitor purple to ground 44vac
    grey to ground 14.7vac
    Charging coil yellow to red/purple 5vac
    Primary voltage from cdi to ignition coil blk/grn & yel/brn to ground 106-110 vDC
    Voltage out of cdi on brown 7.7vdc


    This is a quote from that thread posted by “myself”. This is for a red domestic carbed 700 gen 1. Given these numbers it seems the stator would be my issue. I’m way down on cranking volts on my exciter coil and primary side of the ignition coil.

    Just checked my notes on the late style 700.
    Cranking @11.2 volts gets 5.5vac from excitor and charge both. Then as soon as it hits off to idle the excitor jumps to 40+vac and charge to about 20vac.
    The Gen 1 starts cranking at full voltages and doesn't change at idle. Definitely a bit different between the early and late setups.

    Late style 700 - is that Gen III CDI/stator with the single ignition coil?

    What are the ‘full voltages’ for Gen I ?

    My cranking volts was about 11.6 (cranking with plugs out and wires on plug end holders). So my cranking rpm should be slightly higher then yours during testing. With mine showing cranking vac in the low 4 range I am still leaning towards my stator being the culprit. Unless I am just way off base and not thinking through this correctly.
