1973 Honda CB350F0 · Starting & Charging Buying guide

Choose charging parts around the battery

Two combined rectifier/regulators have different battery requirements. Starter service also includes a terminal boot and seal, useful when the issue is a damaged cover or sealing component rather than the charging circuit.

Allow for the regulator mount

The standard combined unit measures 68 × 94 × 26mm; the lithium-only unit measures 70 × 94 × 27mm. Both have 80mm mounting-hole centers and stock-type plugs. Assess mounting clearance and use the supplied instructions without bypassing the motorcycle’s safety circuits.

Keep starter service targeted

A terminal boot replaces a damaged insulating cover, while the linked starter-motor seal addresses the sealing joint. Neither proves that a no-start problem is inside the motor. Check the actual failed component and compare connections before choosing a relay or a larger assembly.

Starting & Charging questions

Can the lithium regulator charge a lead-acid battery?

No. The lithium-only unit expressly excludes standard lead-acid batteries. Its specified set point is 14V ±0.2; confirm that this also suits the particular lithium battery before purchasing or installing it.

Will the combined regulator bolt straight on?

Custom mounting may be required. Compare the unit’s dimensions and 80mm mounting-hole centers with the available space, then follow its installation instructions. Stock-type plugs do not by themselves guarantee a direct mechanical mounting fit.

Should I order a terminal boot or replace the starter wiring?

Inspect the cover and electrical connection separately. A split rubber boot can be replaced when the terminal and wiring remain sound; damaged connections need their own repair. The separately linked starter seal serves the motor’s sealing joint.
