The thing is, is that I don't know if it's the ground, or a dodgy connection somewhere as it worked fine before!
I should ellaborate on the problem a bit more:
I had the indicators wired up with no problems and were running fine, the problem arose when I turned Hi-Beam on, the wires for the headlights started to melt... so I quickly turned the lights off from the switchgear and it stopped it smoldering!
The weird thing is that it took the left indicator out with it, but only the F-Left. The rear left indicator works fine, and so do both right hand indicators?
The bulb for the indicator doesn't instantly blow, it kind of fills with smoke first and then gradually dies?
EDIT:
Oh, and while inspecting the loom I found this on the side of the carbs, is it a Throttle Position Sensor? And, if it is... does it matter too much if it isn't connected?
