1978 Honda CB750A · Electrical Buying guide
Start with the circuit needing repair and identify the equipment fitted to the 1978 Hondamatic. Keep any previous wiring changes with the repair notes before choosing a model-specific loom, charging unit or ignition component.

Identify the fitted switches, lamps and charging components before replacing the loom. Compare the connectors and mounting arrangement with the intended replacement, especially where previous repairs altered the wiring.
Use the identified repair to decide whether the job needs a harness, charging unit, coil assembly or smaller service part. Compare package contents after that decision, rather than treating neighboring electrical listings as one complete-system kit.
No. Its description specifically limits the application to the 1977–78 CB750A Hondamatic and reference 32100-393-770. Other years and types use different harness references, so compare the loom fitted to this motorcycle before ordering.
The selected 1977–78 CB750A loom replaces 32100-393-770. The separate 1976 Hondamatic loom replaces 32100-393-000 and is restricted to that year. Match the complete reference and fitted wiring; the shared CB750A name does not establish an identical harness.
No. Rick’s explains that an OEM-style regulator’s charging voltage can exceed a lithium-ion battery’s requirements. The selected Hondamatic unit is described as OEM-style, without a lithium-compatible specification. Compare the regulator’s documented charging output with the exact battery’s charging requirements before ordering; model fitment and matching plugs do not settle battery compatibility.
