Motorcycle Questions? Ask a Mechanic.
Hi Nick and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, proposed preliminary tries (if have not been done)
Appreciate the post back.
Does the neutral indicator lights up correctly/as expected?
Still, let's try going back to basics; were you able to run diagnostic?
Bear with me and let's go back to "...green and orange wires..." To my recollection, the green wire on a Honda almost always is tied to ground hence no voltage would be as expected. On the other hand, the orange wire to the shift motor would only be present when attempting to shift. This motor would also go CW and CCW thus the orange wire wire would not always be a +V. With this in mind, there would be another wire to the shift motor but not green.
And do you have an electronic copy of the Service Manual?
Apologies for delays; Internet is sluggish if at all available while mobile.
Could the other wire to the shift motor perhaps be a green/red?
The pure green wire is tied to ground.
These orange and green/red wires provide voltage to the shift motor BUT changes polarity; i.e. to be able to turn the motor clockwise and counter-clockwise to perform the shifting.
When testing for voltage, test between these 2 wires, orange and green/red not to ground nor the green wire and only when attempting to shift.
I understand Nick. Please re-confirm that there is no measurable voltage between these 2 wires (orange & green/red) when attempting to shift.
Very low Ω with the value varying depending on the condition of the carbon brushes and commutator segments. Equally important is that this measured resistance should not change (much) as the motor is manually turned.
Appreciate the post back Nick.
"...some kind of safety device this way you cant shift it if the angle sensor is out of adjustment..."; agree BUT for it not to shift, then there should be NO "...voltage at the shift motor..."
Even if the angle sensor is off adjustment, the mere presence of voltage should cause the motor to partially spin and therefore shift.
What is the value of the "...voltage at the shift motor..."?
And is this voltage ONLY present when attempting to shift?
