Installation Notes
Document wire positions before removing old switch – take photos to ensure correct reconnection. Clean connections and apply dielectric grease to prevent corrosion. Pro tip: if switch replacement doesn’t solve starting issues, check neutral safety switches and starter solenoid connections – these often fail together. Test all positions after installation to make sure everything’s working properly.
