1982 Honda CB900C Custom · Starter & Charging Parts Buying guide
A starter that does not turn, a motor that spins without turning the engine and a battery that will not stay charged point to different checks. Identify the symptom before choosing brushes, a relay, starter-clutch parts or a regulator.

Eight-wire rectifier/regulatorRick’s Electric replacement with two connectors: four-prong/three-wire and six-prong/five-wire.View part
The Mitsuba starter brush set is for the specified two-brush motor; compare the actual motor if it has been replaced. The alternator uses a separate brush pair for the electromagnetic rotor. Starter-clutch rollers, caps and springs belong to the mechanical drive and will not repair a failed relay or battery cable.
Inspect alternator brushes, wiring and connectors and test charging performance before replacing the regulator. The eight-wire 24-2031 unit has four-position/three-wire and six-position/five-wire connectors. Match terminal functions and battery requirements; the separate lithium-only regulator is not an AGM substitute.
Start with the battery under load, battery and ground connections, and the high-current path to the starter. The relay or motor may also be faulty, but a click alone does not prove either needs replacement.
Inspect the mechanical starter drive and starter clutch using the Honda procedure. Rollers, springs or related drive parts may need service; this symptom is different from a motor receiving no electrical power.
No. Poor connections, worn alternator brushes, rotor or stator faults and a damaged battery can also cause poor charging. Test the system before ordering, then verify charging performance after the repair.
