Hi All,
Looking for a bit of help/advice with my 1975 Honda CB400F UK model headlight electrics. I had an issue with my headlight not working (neither headlight nor park light coming on). After investigation I found that there was no voltage to either side of headlight fuse or taillight fuse. Further investigation identified a loose wire under the nest of wires under the tank. This wire appears to be black/yellow. I did fit a David Silver replacement right hand switch some time ago and seem to remember that the wiring for this was not as expected. Looking around the ~nest~ the only place I can see that the wire could have come from is a connector that appears to have a blue and a black wire already in (see picture - loose wire is to left in front of horn and connector, I think it fits, is to the right). When I did put the loose wire into this connector the headlight, park and taillight all worked using the right hand switch so it seems to be correct. I do have the wiring diagram but cannot see a connection /junction that looks like this. So my questions are:-
1. Should the black/yellow wire be connected to black/blue connector.
2. If yes, this connector looks wrong with 2 wires in top (blue and black) and 3 wires in bottom (blue, black and black/yellow). Therefore to tidy up can I separate blue and black wires into their own separate connectors.
3. If 2 is OK to do which connector would I attach black/yellow to, the black connector or the blue connector?
Any help in answering above questions would be much appreciated
