    Red purple is battery power. Gray is limp mode. Yellow..... Unsure

    Also check your battery voltage at the CDI while cranking. Especially if the no spark condition seems like it happened for no reason..... The standard lead acid type batteries are know to drop low on the voltage end.

    You said that the gray wire was hooked to ground. That is incorrect. Gray wires on a Polaris do not go to ground.

    Several comments;
    I did not see the plastic cover for the battery. Make very sure the battery cover is always in place whenever the battery cables are connected. The shell of the electrical box is metal and it will short out if it touches the battery posts.

    Keep the electrical box shell away from the top of the battery whenever the plastic cover is removed.

    You use the term 'splice' several times. How did you 'repair' the Red/Purple wires? The CDI looks like it is the Update Ignition Kit, correct?

    How did you trace the cut gray wire 'that goes to ground'? Physically follow the wire. Where does it go?

    The terminal board has markings for each group of terminals. What is the label beside the cut 'gray' terminal?

    The disconnected Gray wire with the spade connector is for the RPM limit 'limp mode' when the engine overheats. Unplugging it temporarily is one method of diagnosing an unwanted RPM limit during normal riding. Leave it disconnected for now, but know that it should be reconnected after the no-spark condition is resolved. There should be a spade terminal group marked either Tan or GRY, that terminal group will have another tan wire connected, maybe two.

    Battery voltage while cranking is critical. If the battery voltage does not stay well above 10.6 volts while the engine is cranking you will not have spark. Measure this with a multimeter at the battery. A strong battery will maintain something like 11.0 volts or higher while cranking the engine.
