Thanks Simon

1/2.  Green earth is all good, and I also attached feed direct from battery to instrument cluster through the brown white connector and all lit up ok.

3.  Have taken tank off and inspected rubber boot connectors and reconnected. Everything ok except brown /blue wire from headlamp switch which had no female connectors to connect to in loom, so ended up connecting to black loom connector instead (this appears to be in some wiring diagrammes I have.

4.  Works ok when fed from battery +ve.

5.  Have thought of this, and may have to end up doing it anyway.  I always ride with lights on so should be ok.

6.  This is where the wiring diagramme confuses me as there is no brown white wire in the boot, as I believe it is connected within the loom where I can't get at it.

Thanks for all your ideas, appreciated

Just joined.  Have a cb400f2. Instrument lights not working from PO. Removed them, no bulbs fitted, so replaced, still no joy. Removed headlamp and removed wires to brown/white connector and tested for feed after turning on ignition and headlamp switch to on, no joy.

Is there a continuity test I can do from the brown/white wires, or other suggestions?
