1970 Honda CB175K4 · Electrical Buying guide

Start with the circuit and the battery in the bike

Connector shape and battery chemistry are purchase decisions, not details to leave until installation. Record the existing wiring arrangement and battery specification before comparing the featured ignition switch and charging units.

Parts to consider

Honda CB Ignition Switch ~ Replaces 35100-303-007 Round-Plug Ignition SwitchRound connector with six holes and four wires. Compare the connector and terminal positions with the motorcycle’s existing harness.View part Honda CB Hot Shot Rectifier / Regulator ~ Replaces 31400-292-670 Lead-Acid Rectifier/RegulatorRick’s Electric combination unit for standard lead-acid batteries. Not compatible with lithium-ion batteries.View part Honda CB Hot Shot Rectifier/Regulator ~ Lithium Ion Battery Compatible Lithium-Ion Rectifier/RegulatorRick’s Electric lithium-ion unit with a 14 V ±0.2 set point. Confirm that charging specification with the battery maker; not for standard lead-acid batteries.View part

Related parts: 133 mm Battery Hold Band

Treat the battery choice as a charging requirement

The two charging units serve different battery types: standard lead-acid or lithium-ion. Confirm the battery maker’s charging requirements before choosing. The related battery band covers CB175K 1970–71 and measures 133 mm inside bracket to bracket; compare that span with the fitted retaining arrangement.

Record connector details before buying

The featured switch uses a round connector with six holes and four wires. Compare the plug and occupied terminal positions with your harness. If the wiring has been altered, resolve its circuit mapping before ordering; a matching outer plug shape alone does not verify every connection.

Electrical questions

Can either charging unit be used with either battery type?

No. The lead-acid unit excludes lithium-ion batteries, and the lithium-ion unit excludes standard lead-acid batteries. Identify the battery fitted and check its maker’s charging requirements before choosing between them.

What must match on the ignition-switch connector?

Compare the round plug, six-hole layout, four wires and occupied terminal positions with the existing harness. If the harness has been modified, establish the circuit mapping before treating the switch as a replacement.

What mounting space does the lithium-ion regulator require?

Its body measures 54 × 57 × 35 mm. Compare the intended mounting location and cable routing, particularly after a battery-box or harness change; battery compatibility remains a separate check.
