Neutral Diode; Function Inspection - Honda CB HORNET 160R 2015 Shop Manual

ELECTRIC STARTER SYSTEM
POWER INPUT LINE
Connect the starter relay switch 4P (Red) connector.
Turn the ignition switch to "ON".
Measure the voltage between the yellow/Red wire terminal
(+) and ground (–).
If the battery voltage appears only when the starter switch
is pushed, the circuit is normal.

FUNCTION INSPECTION

Remove the starter relay switch (page 18-3).
Connect an ohmmeter to the starter relay switch cable
terminals.
Connect the fully charged 12V battery to the starter relay
switch connector terminals (A and B terminals).
There should be continuity between the cable terminals
while the battery is connected and no continuity when the
battery is disconnected.

NEUTRAL DIODE

INSPECTION
Remove the front cowl (page 2-3).
Release the neutral diode.
Check for continuity between the diode terminals.
When there is continuity, a small resistance value will
register.
If there is continuity in one direction, the diode is normal.
