1986 Honda CB450SC Nighthawk · Starter & Charging System Buying guide

Specify the battery, connection or sealing location for each purchase

The lithium charging option requires a suitable battery and connection comparison. The starter boot and small installation seal serve different service locations. Related body-seal, six-wire regulator and interlock-diode choices should likewise be identified by their written references before ordering.

Parts to consider

1978-86 Honda CB450 / CB400 Rectifier / Regulator ~ Lithium Ion Battery Compatible Battery-specific lithium regulatorThe unit is lithium-ion only, uses 14.0V ±0.2 regulation and omits the black sensing lead. It is expressly unsuitable for a standard lead-acid battery.View part Honda CB Starter Motor Terminal Rubber Boot ~ Replaces 32411-230-000 Starter cable terminal coverOne rubber boot replaces Honda 32411-230-000.

Compare the battery requirement before the regulator connector appearance

The lithium unit’s 14.0V ±0.2 set point must suit the installed lithium-ion battery. Its design also omits the black sensing lead. Confirm both battery requirements and wiring arrangement before purchase. The other listed regulator is identified by six wires across two blocks; its description does not specify a battery chemistry.

Keep starter references with their individual service locations

The large 60 x 1.4mm seal closes the starter body or cover, while the small 24.4 x 3.1mm seal is listed for the compatible installation. The protective boot covers the cable terminal, and the diode belongs to the starter-safety circuit. Identify those needs separately instead of choosing a generic starter repair assortment.

Starter Seals & Charging Match FAQs

What battery details should I confirm when choosing the lithium charging unit?

Confirm a lithium-ion battery and that its requirements accept the stated 14.0V ±0.2 set point. Then compare the connector arrangement, including the omitted black sensing lead. Do not choose this unit for a standard lead-acid battery.

What should I include in the parts assessment when replacing a damaged terminal boot?

Assess the starter cable eye, terminal and connection for heat or corrosion as well as the cover. One rubber boot is supplied, while the cable and terminal nut are separate. Account for any adjoining items needing renewal before completing the order.

Which references distinguish installation-seal work from opening the starter body?

The 24.4 x 3.1mm installation item lists 91312-MG7-003, 91309-300-000 and 91309-425-003. The 60 x 1.4mm body or cover seal lists 31206-286-158 and 31206-402-008. Match the required location in the parts fiche before ordering; the two seal applications should not be chosen by appearance alone.
