ok i'll tell. its from silvertop, and battery was connected while switch was not pluged in, and wire short burnt the switch,, the replacement is orginal Japan made 4afe switch,, with similar bolt on.. and diffirent rear bracket,, for which you simply redo the connection grip,, and your engine check light will go on, along with oil check.. japan made replacement will cost 950Rs. and you have to unscrew power st. pulley to bolt this little thingy.
