Bike won't start

[stevenmamos]

My batter has slowly been dying so I ordered a replacement last week. I continued to ride the bike until the new battery came in, until one day it wouldn't start. All the lights would come on and fuel pump would kick in strong, when when trying to start, you'd hear a "click" from under the seat.

Battery came in today and just replaced it but still having the same issue. I've taken a picture of what is "clicking." I checked both fuses on the sides of it and they look fine. Help please!ImageUploadedByMO Free1355543381.453448.jpg

That would be your starter relay. They are about $70 from Yamaha. Some people have tried the cheap ones you can get on ebay and have not had much luck. Mine is also on its way out but is hangin in there for now. New one is on its way.

So it's the starter relay, NOT the starter?

Correct, the relay transfers the power from the battery to the starter. You can check at the starter and see if it is getting power when the starter button is pressed but most likely your relay is not transferring the juice.

Just use a tester light and touch to the cable connecting to the starter and see if it's getting power when start button is pressed?

Exactly, just touch the lug on the starter where the cable connects with you test lit and give the button a push. If its weak light or no light you aren't getting full voltage. A volt meter is best as it will tell you what actual voltage you are getting at the starter, because if the relay is transferring some power but not enough you may get a test light to light up weakly.

By the way, what year is your bike? Looks like you may have some corrosion on the bracket for your relay there. If any of that corrosion is on the inside of the relay that is definitely the culprit

It's a 2002. Getting ready to head back to the garage and work on it. I'll let you know what I find with voltage and corrosion.

Think Jbat hit on the head but...............

Since you are going to be checking the starter, check the cable itself. We have seen loose cables going to the starter. Tighten it up if necessary (careful, this nut CAN be OVERTIGHTENED)....check for corrosion at the cable connections. Good place for Dielectric Grease.

Also check your connections at the rectifier, if they are loose, battery won't charge....another place for dielectric grease.....lol

Like Jbat said, meter is best, once engine is running, you should see ~13.5-14.2vdc at the battery post and will be less when you turn off the engine.....if so, charging system is in good shape for your new battery.

All I had was a tester light, and even with that I was getting 0 light from it. Took out the starter relay and there was some slight corrosion. Cleaned up up and put it back on but still no luck. Ordered the relay from powersportsplus for $55. Hopefully this fixes the problem!
