Sorry for the mega late reply on this lads, sacrificed internet for the rebuild at the time and just wanted to say (now i remembered :P) Thanks so much for all your help. got it sorted with the loctite in the end and it all worked out! really grateful for the replies. will post some bike porn soon and start getting active! 🙂
Just find the one that’s giving out 12v when the lights are on. Then 12v only when the brake is on. My headlight/taillight doesn’t work unless the engine is running. The brake light works from the battery...
Try doing it ticking over. The black will be the earth. You’ll get it, it’s just a process of elimination 🙂
