Loom 73-0929 references 32100-460-340 and is listed specifically for the 1982 CB650SC. Its package contains one main loom; switches, ignition components, regulator/rectifier, lamps and separate sub-harnesses are excluded. Keep those exclusions in view when planning a wiring replacement.
Coil 17-6803 is sold individually, references 30500-422-003 / 30500-422-013 and requires separate 7 mm high-tension wires. Regulator 24-2030 references 31600-460-731 / 31600-426-000; five wires occupy its six-prong housing and three occupy its four-prong housing.
The coil record supplies replacement references and package details but no primary-resistance specification. Obtain that specification and compare it with the fitted ignition manufacturer’s requirements before choosing the coil for a modified system.
The regulator record describes its connections but does not state battery-chemistry compatibility or charging-voltage limits. Compare the regulator manufacturer’s specification with the fitted battery’s requirements before choosing it for a converted setup.
