1981 Honda CB650C Custom · Electrical Service Parts Buying guide

Keep the coil inventory and fuse-box rating identifiable

The coil supplies attached wires, while the fuse box supplies 15-amp fuses and the regulator has its own two-plug layout. Use those details to identify each purchase without treating package contents as a complete specification for changed wiring.

Check the coil and fuse-box packages

Rick’s coil 24-6011 is sold individually with wires attached. Its record does not establish spark-plug cap inclusion or primary resistance. Fuse box 73-0125 references 38200-MF9-405 and includes 15-amp fuses; identify the fitted box and wiring before choosing the assembly.

Compare the regulator connections separately

Regulator 24-2030 references 31600-460-731 / 31600-426-000. It has five wires in a six-prong housing and three in a four-prong housing. Compare the occupied wire positions as well as the two housing shapes.

Electrical Service Parts questions

Do the supplied 15-amp fuses establish the rating for every circuit?

They describe the fuse-box package, not a circuit-by-circuit specification for the motorcycle or modified wiring. The listing does not supply that circuit map. Check the correct wiring information and required ratings before choosing protection for any changed circuit.

Do matching regulator plugs establish compatibility with a changed battery?

The regulator listing gives its connections and replacement references but no battery-chemistry compatibility or charging-voltage limits. Obtain the regulator manufacturer’s specification and compare it with the fitted battery’s requirements before choosing it for a converted setup.
