Sandra, your fuse box is located under the right side cover(as you sit on the bike) directly behind the fuse box is where the flasher relay is located. I'll put a link so you can have the service manual if you don't have the original. your original would be located in the box, under the left side cover. I will also give you a picture of an OEM flasher relay so you know exactly what to look for. Good luck.

start relay should be checked, if cables are loose or corroded they do not deliver enough power.if jumping the start relay will engage the starter replace the relay.
