1978 Honda CB750A · Electrical Buying guide

Start with the Hondamatic assembly and its connections

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.

Parts to consider

1977-78 Honda CB750A Wire Harness ~ Replaces 32100-393-770

Hondamatic main wiring loomMain harness referencing 32100-393-770, specifically listed for the 1977–78 CB750A Hondamatic.View part

Two coils mounted on bracketsStock-type pair referencing 30500-300-013. The description lists two coils already mounted on their brackets.View part

1976-78 Honda CB750A Rectifier/Regulator

Hondamatic combined charging unitRick’s Electric regulator/rectifier for the 1976–78 CB750A, with OE plugs and installation instructions listed.View part

Record the retained electrical equipment

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.

Plan the separate assemblies from the diagnosed fault

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.

Common questions

Is the main harness a general CB750 replacement?

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.

Which reference distinguishes the 1976 loom from the 1977–78 loom?

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.

Does the Hondamatic application alone establish compatibility with a lithium-ion battery?

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.
