I bought this as a Scooter with no Spark. I replaced Ignition switch.Starter switch, Starter Relay,Stator,Ignition Coil,Pick Up Coil,Battery,CDI Unit AC, And New Wiring Harness.No spark Grd is good.But noticed 4 th wire on the 3 Phase Stator that is a Red and Blk wire. But plugs in no where. So I inserted a test light into it. And when you crank Engine over it pulsates . So does this wire need to be connected somewhere,.?And the CDI box has a 4 plug and a 2 plug .But only 1 wire is used on the 2 plug Harness. But CDI has a terminal has 2 terminals. ? The Kickstand safety switch is good. But there is another switch mounted on the upper part of frame on left side.Called a Parking Brake switch that is working too.But what is the purpose of that.? Has a 4 pin pug going to it.And 1 wire goes to CDI box.
