bungie Posted May 5, 2005 Report Share Posted May 5, 2005 I have a tys125f (sy125f) and when i brought it had a partial wiring loom.I need a rear brake light so i decided to fit it and add the extra wiring.I also wired up the horn,kill switch and ignition and brake light from hand and foot.All was well and all worked untill i revved the bike up and it popped the bulb.tried another and on tickover ok but when revved it popped.I guess it's that alloy finned thing i left out because i didn't know where it went ! ( i know rectifiyer / regulator i think ) i cannot get any info on wiring it in ( sh620b-12 ) is the number on it. If i am looking at the front of this with fins at the top the plug at the bottom shows top left a black wire,bottom left a yellow wire,top right a red/white wire and nothing in bottom right. There are the same colours on the bike on the original loom /cdi i think but did not want to just fit this incase i bugger something up. Any help would be very much appreaciated so i can get my bike registered and have some fun. Quote Link to comment Share on other sites More sharing options...
