1981 Honda CB750F Starting & Charging Assemblies

Starting and charging service can call for a complete motor, a regulator/rectifier or a brush pair, each with its own application. On this CB750F, identify the component actually fitted before choosing. Starter brushes and alternator brushes are different products with different dimensions and contents.

1981 Honda CB750F · Starter & Charging Starter and charging buying guide

Choose service parts for the installed electrical assemblies

A starter motor, alternator brush set and regulator/rectifier serve different parts of the starting and charging system. Identify the assembly being repaired and compare its reference, connections and mounting before ordering. Battery chemistry is also part of the regulator choice.

Check the starter before ordering its brushes

Starter brush set 24-2021 is for a Mitsuba two-brush motor. It contains two 12 × 14 × 6 mm brushes, one with insulated leads and one with non-insulated leads. That specific motor requirement must be checked if a replacement starter has been fitted; the motorcycle application alone does not establish the brush design.

Separate starter-clutch work from motor service

Kit 24-5001 supplies three 15 × 13 mm rollers, three 15.5 × 6.2 mm caps and three springs for one compatible starter clutch. This is the kit’s repair scope, distinct from the complete motor and electrical brush products above.

Common questions

What must match when choosing a regulator for a lithium battery?

Confirm that the battery manufacturer approves the regulator’s charging set point for the chosen battery. Unit 24-6006 lists the 1979–82 CB750F and specifies 14.0 V ±0.2 V, but that model application alone does not establish battery compatibility. This unit is expressly for compatible lithium-ion batteries and must not be used with a conventional lead-acid battery.

Which relay is the separately sold pigtail intended to fit?

Pigtail 11-2098 is specified for starter relays 24-2004 and 73-0824; both relay listings identify that connector as a separate purchase. The pigtail supplier warns that wire colours do not guarantee terminal orientation. Identify the installed relay and verify the wiring-diagram and terminal arrangement before connection.
