The Hawk’s CDI ignition and electric starter are separate parts of the electrical system. A motor that cranks without firing needs a different diagnosis from one that will not crank. Use the correct Honda wiring diagram and test the suspect circuit before replacing its components.
A replacement box cannot repair damaged terminals elsewhere in the loom. Compare the ignition switch’s six-terminal rectangular block and the regulator’s two connectors with the existing wiring. The related lithium-only regulator has a different battery requirement; select it only after checking the battery maker’s charging specification.
This switch is intended for the rectangular block with six flat male terminals. Compare that block and the lock mounting on your Hawk, especially if the harness or instrument bracket has been replaced.
