Good day,
Information on the White wire. The white wire is for killing the power on the primary ignition power generating coil without directly connecting to the primary ignition power generating coil. The white wire coil is reverse wound in order to acomplish this. Current flow through the white wire coil produces a magnetic field that cancels the magnetic field of the primary ignition power generating coil. This is done to prevent damage to the CDI. Directly shorting the primary ignition power generating coil for stopping the engine runs the risk of damaging the CDI.
Short version is, READ YOUR MANUAL, it says the white wire is for the ignition kill.
If you chose to use the white wire for power then the power drawn from this circuit will be a direct porportional loss to the power supplied by the primary ignition power generating coil.
Figured I would post this to help clarify the confusion.
