How are CB750 K1 Rear Turn Signals Grounded?
« on: January 22, 2013, 06:15:55 PM »
I'm looking at pictures of K1's trying to see how the rear turn signals are grounded, but can't see enough
detail in the pictures.  Looks like the ground wire connects to the bottom of the turn signal housing itself on the
bolt that clamps them on.  Can't make out how the wire is routed after that.

Ground from that nut on signal connects to green (ground) under seat between battery and fender (where all the rear fender wires go).

I'll refine my question a little.   I know where it connects to the harness.  I was wondering about the route the wire takes
from the turn signal to the connector.   Looks like after coming off the bottom of the turn signal it just goes back behind
the turn signal bracket and through that little clip on the side of the rear fender and then up to the connector.  I don't have
those ground wires, so am going to have to make some and just want to get the correct length and routing.  I know it seems
simple, but there are several ways it could go and I want to get it back to how it was originally routed from the factory.

Yes you are correct about the routing. The wire connects to the bolt holding the signal onto the frame by an eye connector at the end of the wire. It then goes around that tab on the fender you mentioned and then up to the top center section of the fender. From there it routes forward under the frame support for the fender where it plugs into the green wires of the harness. To be correct, these wires are black but they plug into the green wires of the harness at the same location the blue and orange blinker signal wires connect. You need to crimp that tab on the fender to keep the wires routed in place.
