1970 Honda CB350K2 · Starter & Charging Buying guide
The female-connector rectifier and the two battery-specific combined units are different choices. Match the existing wiring and stator, then settle battery chemistry before planning any change to the charging system.

The replacement rectifier addresses one part of the original arrangement. The combined units provide both rectification and regulation and are specified for use with the stock stator. Check the manufacturer’s instructions against the existing wiring before changing from the separate-component layout.
The linked starter cable is sold each and replaces Honda 32410-286-000. Compare its route and terminal ends before ordering. The linked terminal boot protects the connection, while the 60 × 1.4 seal is a separate motor service part; neither diagnoses a worn starter.
The individual female-connector product is a rectifier. Honda’s K2 catalog identifies a separate regulator. If you want both functions in one component, choose an appropriate combined rectifier/regulator and follow its wiring instructions.
Use the lithium-ion version only after your battery manufacturer approves its 14V ±0.2V set point. It is not for standard lead-acid batteries. The lead-acid combined unit is likewise not suitable for a lithium-ion battery.
Inspect the existing cable’s insulation, terminal ends and route first. The linked replacement is sold individually and references Honda 32410-286-000. Replace it when its condition or fit calls for it, rather than assuming every starter fault requires a cable.
