zombie i cannot thank you enough .... ive learned so much in the short time my son has owned this bike , and im pretty sure ill have a whole lot of other things to learn before it goes ... thanks again ..

hi , coming from the scooter the plug with the red and green wires to it is the positive and negative , both of these on my sons bike are showing constant live ,12.78 v.. , it shows exactly the same when the ignition is on but rises when the scooter is started , the black box beside the wiring in the picture is the exact same box as ours and as far as my research has gone the wire with the bullet head is a direct link to the cdi , the cdi supposedly sends a pulse to the l.c.u through this box and varies volts depending on how high you are revving or if you pull up at lights it drops the current so that your headlights arent drawing 12 v , the other wires you see in the picture (the ones that are bridged) these i think are a direct current to the headlights , the site i stole that picture off gave the bridged wires as a solution to the headlight issue but im not sure just bridging wires is whats best for the rest of the wiring loom , i spoke with some people who own bikes and they said the direct constant 12v current to the l.c.u is right and that there is some sort of switch inside the box , it makes sense i suppose because the battery is never drained , id be more interested to hear someone who is more used to this sort of system to find out your views , and or if you think you could sort out some sort of relay system to save me a few quid lol ...thanks zombie and everyone else for your patience but if we can solve it im sure it will help alot of other people , if you google this problem there are alot of people with the same problem ...thanks..

right guys i had to bite the bullet and buy the part , i wont have it delivered for a few days , my biggest fear is i plug it in and it gets fried or something , how can i check my headlight circuit hasnt got a short that will fry it , ill remind you of how i got to this stage , the bikes lights all worked , my son parked it up for a few weeks , he put a trickle charger on it , we went back to start it it started no problems but the headlights had stopped working , i noticed that one of the 7amp fuses in next to the battery had blown , i removed parts and replaced fuses until they stopped blowing , i ended up with the l.c.u i never noticed it was cracked because of the rubber cover over it  , once removed the bike stopped blowing the fuses , when i plugged it back in it blew the fuse and blistered the plastic housing next to the crack .. with the new part enroute at a now cost of £70 you can understand why i am apprehensive everytime i call them the price goes up a little haha, do you think im being paranoid and it should simply be a plug in and away you go , or am i rite to be cautious ...either way thanks for all the info folks...

thanks again for the replies folks , i contacted kymco uk today and the part is a headlight control relay , approx £60 to buy , interesting reading that you had a similar experience and had to re-wire direct to lights and install a switch , if this doesnt work i may have to go down that route ...thanks ..

this is a couple of pictures of it

im having a nightmare lol , the cdi in my sond bike has a four and two pin plug with a wire coming off the box itself , i have looked everywhere and cant find another cdi (not even a picture) with that wire coming from the box ... i cintacted a garage and they said they can sell me one without the wire but surely it must be used for something or it wouldnt be there ... help .. haha

owft ... took off the plastics ..nightmare lol... had a good look around the wires and cant see anything.. i think im going to have to get someone a little more clued up to have a look ....

quick update , i had a look in where the battery is housed and their are three fuses , 1 with black wire and two with red , one of the red wired ones (7amp) had blown , i changed this and started bike , still no lights , checked the fuse and it had blown again ... stumped...
