Rear light wiring??

[Dickyboy]

So the brake light works fine, the side lights work fine and the headlight works fine but the tail light only works with side lights & not with the headlight, which is rather odd. Any ideas what I should start looking at?

Hi,
A question. When the taillight goes out, does the pilot light in the headlamp also go out?
If it does then the fault is likely to be within the handlebar switch - the off/pilot/headlamp one.
ie, when the switch is moved from pilot to full headlamp, it is disconnecting the power from the pilot/tail circuit.
If it is just the tail lamp, then the fault must be in the wiring/ connections. Eg. Are the 3 wires on the tail light unit connected correctly?
Hope this helps,
George

Have you got the original ignition switch? Can you turn it one more turn. Reason I ask is that I fitted a non standard one to replace a faulty original and there is an extra position.
The first turn activates all circuits except tail. Second position - full lighting. A bit of a nuisance but am used to it.

Well that was pretty simple, John had it in one, the ignition switch has a second location & all lighting works, amazing, now to get to work on the odometer trip reset....

Let me know how/if you sort the trip meter!

Tim, yes trip meter sorted, disconnected Speedo drive and lights, then top nut around trip meter knob so I could remove clocks & cable in one piece, checked trip reset actually worked & then oiled & wiggled cable quite a bit as it kind of gets frozen in one position then refitted - the knob works anti clockwise & requires a decent force to turn it now but it does work
