The 1972 CB350F0 combines four-cylinder ignition with separate starting, charging and lighting circuits. Start with the circuit that needs repair, then compare the motorcycle’s present wiring and hardware. A replacement loom, coil set and charging conversion solve different problems.

A stock CB350F uses two ignition coils and contact breakers. Decades of wiring repairs or electronic conversions can change what fits, so identify the installed equipment before buying electrical assemblies.
The CB350F main loom replaces reference 32100-333-000. The linked alternator harness serves the stator and field coil instead. Compare damaged branches, connectors and earlier splices before deciding whether the repair calls for one harness or a broader rewire.
Inventory the existing ignition first
Honda’s original four-cylinder system has two contact breakers and two dual-output coils. The featured replacement-style coil set includes four plug caps and mounting hardware. Record any electronic conversion already fitted, because its coil requirements matter more than the motorcycle’s year alone.
Buying questions
Does the coil set also include spark plugs?
No. It contains two coils, two straight plug caps, two angled caps, and mounting bolts and nuts. The caps connect to the plugs; new spark plugs are a separate purchase.
Will a replacement loom undo earlier modifications?
A model-specific loom provides the replacement wiring assembly, but changed switches, lamps or ignition equipment still need matching connections. Compare those components with the CB350F wiring diagram before treating a loom change as a complete solution.
Can I choose either regulator for a lithium battery?
Choose a regulator specifically compatible with the battery maker’s charging requirements. The lithium-specific option has a stated 14V ±0.2 set point and is expressly unsuitable for standard lead-acid batteries; confirm compatibility before ordering.
