Starter Relay 7 Years, 3 Months ago  
When I push the starter button nothing happens except a clicking from what I'm pretty sure is the compression solenoid. Battery is fine and starter will spin like a top if a jumper is ran directly to it. There is no current at the starter while start button is pressed.
I think the starter relay is my problem but don't know enough about it to troubleshoot. The battery connects to one side of it and the other side isn't hot even when the start button is pressed.
I have taken it off and it has no continuity between left and right side. I also checed the fuses and both are good.
Was wondering if somebody knows an easy way to test it before I start changing parts.

Page 7-21 of the service manual has a diagram on how to test the starter relay.

Positive probe to red
Negative probe to black

No continuity then replace.

Re:Starter Relay 7 Years, 3 Months ago  
Razor, just had the same thing happen to me. I ended up replacing both the starter rely and the relay. I did the continuity check as explained in the service manual and both were bad. The Starter Relay was $39 and the Rely (on the opposite side of the bike) was $73 from the stealership.

I would recommend unhooking the main power wire directly on the starter before you replace either relay and hit the switch a few times after you replaced it/them...here is why. The tech at the dealer told me to do the same thing and I thought he was crazy, so being me, I replaced the starter relay and the relay, hooked the battery up, hit the starter switch and had a run-a-way starter. It kept cranking until I got the wire off the battery...the tech said it has something to do when ever you jump the starter straight from the battery and the solenoid acting on its on.

I disconnected the starter wire, hooked up battery again and hit the starter switch , heard it click, hooked main power back to the starter and it cranked just fine. Hope this helps.

Re:Starter Relay 7 Years, 3 Months ago  
Thanks to both of you. I'm not very good at reading diagrams but as near as I could tell by reading the service manual I'm supposed to disconnect the wireing harness from the starter relay and check continuity between the red wire going directly to the battery and the other wire which I assume goes to the starter. I did this and it has continuity so It should be good if I checked it at the right place. If anybody is familiar with checking this please confirm this for me.
Lew, I'm not sure what your calling "relay" on the opposite side is. Does it have another name ? In the meantime I'll take the other cover off and see if I can tell what your talking about.

Sounds like you got it.

Under the right side cover you'll find 2 black relays; one is the signal relay and the other is the relay unit you want.

It's called the Relay Assy Item number #38 on the Yamaha Electrical Parts page #2

The actual part number is..3EN-81950-00-00 - -RELAY ASSY.


Hope this helps.

Re:Starter Relay 7 Years, 3 Months ago  
Ok, I have pulled the cover and found it. I believe that it's called the "relay unit". I know it's the one located the closest to the outside cover but I'm a little confused now that I look at the service manual.
On page 7-20 it shows a "relay unit" (starting circuit cutoff relay) and a "relay unit" (diode)". Both of the diagrams look the same or look like it's talking about the same relay, but with two different names as well as ways to test it. I think it's talking about testing two different ways on the same relay but was wondering if someone could confirm this.

That's correct.

The relay unit controls more than one thing so you need to test Steps 4 and 5.

Ok, I assume that steps four and five are to be tested at the same location

Re:Starter Relay 7 Years, 3 Months ago  
Ok, I've tested the starter relay under the left side cover, and the relay unit under the right side cover as described in step four and five (page 7-20 of the service manual. Everything shows to be working properly.
I'm going to check the diode while I've got the right side cover off and then I'm off to find the main switch.
