Faulty indicator

[midden]

Any of you come across this problem I'd be grateful for your opinion
[size=78%] Indicators[/size]
                Left front not working neither is the left arrow display  Left rear is working.

                Right front, rear and right indicator arrow work

                Hazards on, the three working indicators and right arrow flashes.




  If I remove either or both of the front left indicator connections the the left display arrow works
The indicator bulb isn't blown, I connected it direct to battery.





Getting a fluctuating Voltage through the left indicator wires with indicator disconnected


Continuity showing between frame and all eight wires in turn  with all indicators connected
fully disconnect left indicator, of the eight wires all but the front left brown shows continuity to the frame
fully disconnect right front indicator and both both right wires show continuity to the frame

Is the problem therefore with the single brown wire?  should all the wires be earthing to the frame?   

Any ideas appreciated
