Yamaha YZF-R15 :: Blown Fuse Replacement


"Yawn..." you might think, "is this a topic that needs introduction or a HOWTO?"

Well, try doing it the first time without guidance and you will know. Even with guidance, if you try to do what I show you below just to check it out, you'll be happier to have known how to get this task done when you get stranded.

It took me about 40 minutes to locate the fuse when my bike has shown no signs of life once. Thankfully that was about 11 am and I was at home. Imagine a situation we faced on a tour - no electricals work, in middle of an almost deserted highway at 8 pm - a small ghat section, don't know what is around and the next known town is over 20 KM away - don't know the road condition. It helps to know how to get things done quickly. (Well, that problem didn't occur to an R15. But then, does it really matter which bike it was in such a situation?)

Well, just before getting into the actual HOWTO section, let us see how to determine if a fuse is blown.

1) The obvious: your console will not light up and just about nothing works on the R15.
2) Before checking the fuse, check your ECU. Whether it is in place and whether the cables connecting to it are fastened properly.
(it happened to me today while cleaning the bike and hence this thread came up)

Now, for the HOWTO part

Tools Needed:
a) The bike Key
b) your hands
c) some gentleness with the tasks you perform


1) The fuse is located under the seat and beside the battery. Please open up the seat and locate it with the help of the below image.



Now, for you to understand why I said it is it is a tricky job: Now that you know where the fuse box is, try locating the fuse there without reading further instructions!

BTW, what you see there is a spare fuse and not the working fuse. Many people reported that their spare fuse is missing. Even mine went missing once (let us not discuss the reasons here!). Thankfully I had a few extra fuses I bought for Rs 4 or 5 each and I have placed one in there.



2) Gently hold the fuse unit as shown in the picture and pull it up



3) You have to pull the unit further up by turning the wire from below the frame - as shown in the picture. The wire is hard and it doesn't allow you to pull the unit up unless you make some room there.



4) Turn the fuse box sideways to see the bottom part. See in the picture below the RED colour socket. The fuse is in there.



5) As shown in the picture, hold the clips on both the sides and gently pull out the red colour socket.



6) There you see the fuse.
Remember, this is a 20 Amp fuse. These fuses are colour coded. A 20 amp fuse has yellow colour.



7) The fuse is push in and pull out type. But please be gentle with your actions as vigorous actions can spoil the connections.



8) This is how the fuse looks like:
The metal arc is like the fuse wire and will be cut for a blown fuse.



A Blown fuse:
Check the arc cut.



Top view of the fuse:
Check the "20" inscribed to indicate it is a 20 Amp fuse.



PS: Fuses need not look the same. If you notice in my above pictures, my spare fuse is different. It shows the blown out part from top view and on the non-transparent sides the Amp's is written. Don't know why but that costed me Rs 6 as against Rs 5 for the normal one. When I bought that the transparent ones for 20 Amp were out of stock.

9) Replace the fuse as needed. Make sure the fuse fits in properly.
Then close the fuse cover (red colour socket) gently into its place. Make sure clips on both the sides are locked.

10) Place the whole unit back into its socket. Make sure the rubber sleeves made for holding the unit are properly placed into their holders on both the sides.



11) Make sure the RED colour wire you have pulled from below the frame sits back into its position.

12) Almost every time you place the fuse box in place the Battery's positive terminal rubber cap gets displaced. Pull it a little and set it into its position.

Thank you.

Please excuse the out of focus photos. If you find some more inputs please post them or let me know and I shall incorporate them into this post.

There are few more fuse boxes at the rear of the bike. They lie inside a rubber cover between the tail lamp and the seat lock under the seat. I have once tried to check for the fuses there but didn't find any. Will check again and add it here if there's any.

And finally, please vote for usefulness of this article.

I just opened up the seat today and was searching for the fuse! I even pulled out the spare fuse thinking it to be the one. Finally, unable to locate it, put it back deciding to find it some other day!

Finally I could locate it with this DIY!

And, those boxes at the end near the tail lamps are the relays for turn indicator, radiator fan and stater motor. This bike has only one fuse.

Just wanted to know, If fuse is avialable only in higher end bikes like R15,Honda CBR 250, Ninja 250 or is it available in all bikes.

I assumed that fuse is present only in FI bikes and not in carbs....

@Hydbiker - very detailed & useful writeup sir'jee . While all motorcycle wiring schemes that I know have a fuse unit , this one is a bit over-engineered imho .
