Question about 2008 Honda CBR 600 RR
The speed sensor next the starter motor
sends a voltage pulse to the speedometer.
If you can get at the connectors
just down from the speedo you can
check for this pulse.
Block the back wheel off the ground.
Unplug the connectors and hook
a volt meter to the pink/green +
and the green/black - wires
on the harness side not the speedo side.
Turn on the key and then
check for a 0-5 volt pulse
when you turn the wheel forward
If you have a pulse the speed sensor
is likely okay and your speedo
circuit board is faulty.
If you get no voltage pulse then you have
to check the pulse closer to the
speed sensor or check the connectors
and wires for faults.
No pulse can be a faulty speed sensor
or just a bad connection.
Have you checked the fuses well?
