So after sorting the starting problem here I am, Fuelled up, Tyres up, Climbed up, Spirits up and..............No lights!! power supply is there, connections are good, checked wiring for breaks, damage and wear, fitted new lamps today, front lamp now works (but not the side light) nothing on the rear light / brake light.
As electrics are a black art to me I don’t expect an easy resolve but any advise that point me in the right direction would be appreciated (bearing in mind you are replying to an electrically dyslectic idiot).
Edd.

So your brake light does not work? forget the other stuff for & min, when you pull either the front or rear brake nothing happens is that correct?

Mezo.

Yes, Nothing from the hand or foot levers, I know power is running to it, and I have replaced the rear lamp twice.
Edd.

Indicators are working?
Look there is a black double pin socket in the loom,if any of those two are doing a false contact then it will do that.

Hi 55w, Indicators working well, I will have a look for this double pin to-night.
Cheers Edd.

All that faffing about and it turned out to be the earth wire to the back light unit,
looked ok at first, then found the wire had parted from the holder but the outer sleeve was firmly fix.
Out come; don’t believe your eyes with electrical connections.
Thanks for the diagram Mezo.
Edd.
