1969 Honda CB175K3 · Starter & Charging Buying guide

Separate starter-circuit repairs from charging choices

The starter solenoid switches the starting circuit; the rectifier/regulator serves the charging system. Identify which system needs attention, then compare the relevant connections and battery requirements before selecting a replacement.

Match battery chemistry and charging requirements

Use the lead-acid rectifier/regulator with a standard lead-acid battery. The separate lithium-ion unit has a 14 V ±0.2 set point and must meet the chosen battery’s requirements. Its 54 × 57 × 35 mm dimensions also matter if the original mounting location has changed.

Compare the starter relay as a separate assembly

The starter relay replaces references 35850-371-670, 35850-306-670 and 35850-HA7-670. Compare its mounting and connections with the installed assembly. On a modified harness, use the relevant wiring diagram and service checks to identify the fault and terminal functions before selecting a replacement.

Starter and charging questions

Which unit is for a standard lead-acid battery?

Choose the standard lead-acid rectifier/regulator after checking the existing wiring and stator application. It is not compatible with lithium-ion batteries; the lithium-ion version is a separate product.

Does lithium-ion compatibility cover every battery?

Confirm your battery maker allows a 14 V ±0.2 charging set point. The lithium-ion label alone does not replace the specific battery’s charging requirements and installation instructions.

Is the replacement starter solenoid polarity-sensitive?

The replacement solenoid is specified as not polarity-sensitive. Still identify the terminal functions using the applicable wiring diagram and compare the mounting and connections, particularly on a repaired or modified harness.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
