1966 Honda CB160 · Electrical Buying guide

Choose electrical parts around the repair you need

The featured charging units both include the 1966 CB160 in their application. Battery chemistry is the deciding difference. If the wiring or battery has been changed, check the complete charging combination rather than relying on appearance.

Charging units to compare

Honda CB Hot Shot Rectifier / Regulator ~ Replaces 31400-292-670 Lead-acid Hot Shot rectifier/regulatorFor standard lead-acid batteries only. A combination rectifier/regulator for the listed 1966 CB160 application; do not use it with a lithium-ion battery.View part Honda CB Hot Shot Rectifier/Regulator ~ Lithium Ion Battery Compatible Lithium-ion Hot Shot rectifier/regulatorLithium-ion version with a 14 V ±0.2 set point and a 54 × 57 × 35 mm body. Check that set point against your battery’s charging requirements.View part

Separate a charging repair from an ignition repair

A rectifier/regulator is a charging-system component. If the symptoms involve starting or running, identify the faulty system before ordering. Use the appropriate service information to distinguish a battery or charging problem from ignition trouble; replacing a charging unit does not renew the ignition components.

Choose for the battery that will remain on the bike

Select the lead-acid version for a standard lead-acid battery. If the bike is being converted to lithium-ion, choose the corresponding regulator only after checking the battery’s charging requirements. The lithium unit’s 14 V ±0.2 set point is the specification to compare, rather than the battery’s nominal voltage alone.

Electrical buying questions

Which version should I choose if I am keeping a lead-acid battery?

Choose the standard lead-acid Hot Shot version. The lithium-ion version specifically excludes standard lead-acid batteries, so the two units should not be treated as interchangeable choices for the same battery.

Will the charging unit suit a bike with replacement wiring?

The application includes the 1966 CB160, but a replacement harness may use different connections. Compare the fitted plugs, terminals and mounting arrangement with the unit’s instructions before ordering for a rewired bike.

Can I change to lithium-ion and keep the lead-acid regulator?

This lead-acid Hot Shot unit is explicitly incompatible with lithium-ion batteries. Review the battery and regulator together before changing chemistry, including the lithium battery maker’s permitted charging voltage.
