Frequently Asked Questions

What does Honda starter clutch diode 31700-124-003 do?

It is the diode/rectifier in the starter-safety circuit, isolating the clutch and neutral paths so current does not feed backward through the interlock wiring.

Is part 24-2044 a charging-system rectifier?

No. It is the starter clutch safety-circuit diode that cross-references Honda 31700-124-003 and 31700-166-008, not the motorcycle's main charging rectifier.

How many starter clutch diodes are used per motorcycle?

One diode assembly is included and one is used in each compatible starter-interlock circuit.
