So I picked up a project viper 700 and its having a weird spark issue. When you turn over the sled with the electric start there is no spark until i let off the key then all three plugs will spark then stop. I think its a stator problem because the flywheel was pretty rusty from sitting so we cleaned the flywheel up and still the same issue. Could my issue be in the E start circuit? any one else have this issue?

Any help would be great..

might be the ignition switch being corroded in the start position for the spark not working under cranking. i would leave the key in the run position and see if it starts in the run position by using a jumper wire across the starter solenoid.

So the spark issue is resolved with a new stator but now there is a new problem. the sled will idle fine but the dash and lights will not turn on. Now the sled will cut out if you give it throttle. Now here's the weird part if you get it above 3k rpm all the lights work sounds healthy but you fall below that rpm the machine shuts off. Could this be from a harness rub thru? I guess ill check that next...

Harness rub through is a possibility. Stator even new could be bad. Did you use a OEM stator or aftermarket? Aftermarket for these sleds are known to be bad right out of box unfortunately. OEM is the only way to go with this part.
