Thanks for this. The kill switch was connected but I have disconnected that. I have cleaned up all of the connections to the CDI (the CDI was not connected when I got it) and earths that I need and with a new plug and it sounds like I have a spark. There is no 2 stroke oil in it or fuel pipe so I will need to get these. I may have to wait until it gets dark and then kick it over with the plug out but earthed to see if I am right about the spark. Thanks for the information so far. I sent my other half and her kids off to the pictures so I can get some time with the bike. I only brought it yesterday and love it. Non starter and rough as old boots or not. Cheers but I am sure that I will be asking more questions in the future. Bad wiring pictures below

By butchered I mean that the bike has been used off road and no battery no, presumibly a total loss system? There is no headlight and a lot of the wiring is connected by connector blocks. The frame starts 2k4 (The frame and engine numbers are matching) As per the picture I have Green, Yellow, Brown, Red/White and Black coming from the Mag. The orange appears to run to the CDI which has 2 sets of 3 wires. Brown, Black and White/Red and Orange, Black/White and Black. The Orange wire appears to go to the coil which has 1 LV wire. If I put a 6v tester to the mag and earth and kick over there is power from the mag from the Brown wire. The rest appear not to be producing power but this may be down to a bad connection. I cant really test for a spark as I need to shhot out to get a spark plug spanner as I don't have one but should I be getting any juice from anything but the brown? Thanks

I do have the 6 wires from the CDI bunched into 2 sets of 3. All I need now is to work out what I need to connect as the wiring is butchered.

The one I brought today has a 5 wire also I have just posted in another thread to see if someone can help me out with the wiring.

Hi, This is my first post so nice to meet you all. I need some help with a DT175mx (I think. 1981 and the frame starts with2k4). The bike has no battery and someone has wired it so it runs with a total loss system. I have seen some online wiring diagrams however my bike seems to have more wires than the diagrams. The wires from the crank look like this The coil looks like this and the CDI (I dont know if this is right). looks like this I would assume that the green wire from the crank goes to the coil but what about earths etc??? Thanks.
