1979 Honda CB400TII Hawk II Starter & Charging

The 1979 Hawk II has an electric starter as well as a kickstarter. Separate a starting fault from a charging fault before ordering. Compare the starter relay at its connections, and choose a regulator only after identifying the battery and harness arrangement.

1979 Honda CB400TII Hawk II · Starter & Charging Buying guide

Keep starting diagnosis separate from charging choice

A starter relay, rectifier/regulator and lithium-specific regulator address different requirements. The related boot, seal and diode offer smaller service items when their locations and condition match the repair.

Parts to consider

1978-86 Honda CB450 / CB400 Rectifier / Regulator ~ Replaces 31600-KV8-681 Six-wire rectifier/regulatorTwo connector blocks carry six wires: three yellow wires together and three wires in a four-position block. Match the complete connection arrangement.View part 1978-86 Honda CB450 / CB400 Rectifier / Regulator ~ Lithium Ion Battery Compatible Lithium-only rectifier/regulatorRick’s lithium-ion regulator uses a 14 V ±0.2 set point and omits the black signal wire.

Confirm the lithium charging requirement

Rick’s lists the 1979 Hawk application for its lithium-compatible unit, but battery approval still matters. The manufacturer specifies 14 V ±0.2 and no black signal wire. Confirm that set point with the battery maker and compare the supplied connections before selecting it for a conversion.

Inspect smaller parts during starter service

Inspect the terminal insulation and seal condition when the starter is being serviced. The related rubber boot covers the starter terminal, while the related seal is identified as 60 × 1.4. The linked diode is an electrical circuit component; select each item for a diagnosed need.

Common buying questions

Is the six-wire regulator approved for my lithium battery?

Its product information does not establish lithium compatibility. For a lithium conversion, consider the explicitly lithium-only option only after the battery manufacturer confirms that its 14 V ±0.2 set point is suitable.

Why does the lithium regulator have no black signal wire?

That omission is part of Rick’s documented design. Compare the complete connector arrangement and follow its application guidance; do not add or rearrange wires based solely on the appearance of the original unit.

Should a clicking starter make me order the relay immediately?

Check the battery condition, cable connections and starting circuit before choosing a relay. The replacement covers the 1979 CB400TII, but a click by itself does not identify the failed component or rule out other starting faults.
