Main Fuse a Blowin'

[squirrel_hunter]

Right had a quick search and have read the electrics dead... post which is similar however, my main fuse just keeps on blowing! So while I sit here and wait for the AA, your suggestions please:

The main fuse blew on Wednesday on the way to work, replaced with the spare.

The main fuse blew today on the way to work, replaced with the spare.

The main fuse blew again today as I tried to leave work!

The problem is the replacement I have for it is now blowing as soon as I put it in. Its even sparking as I put it in. This tells me there is something seriously wrong.

I know the wiring can rub around the rear sub-frame, and I always check this when I have the plastics off (quite regularly) so I don't think its that or it could be recent. So when I get recovered back home what else should I be looking out for? And why is it blowing with out the ignition being turned on? And how do I turn the f**king alarm off (DataTool System3)?

:oops:

The AA guy came out (nice guy and CBR600RR5 rider) and we had a look, got to the battery to check the wiring around the sub-frame and found one of the alarm wires was exposed. So we wrapped that up replaced the fuse and it fired up. Simple I think... so with the engine running we start to put it back together. As soon as the left hand seat bolt went in bang the fuse went. And sure enough the wiring by the frame was exposed and the bolt was shorting it out. Tapped that up and put it back together and rode home.

Bit embarrassed as I was sure it wouldn't be that as I always check the wires when I have the seat off. I even moved the wires to where I thought they were out of the way, but they weren't!

So I will stick some more tape round it, reposition it and then I will cut the bolt down to size :evil:

Glad you were able to get this sorted, but it's wrong to assume replacing a blown fuse without finding the cause will fix anything, indeed it's almost always bound to lead to at minimum the same happening again or even an electrical fire which could write off the bike :shock: .

It's rare a bike will break without giving some sign beforehand it some way, be it a new vibration, blown fuse, new noise. getting to know the bikes normal noises and feel will make it far more apparent when something changes and if you don't know what it means; just ask on here.

Listening to your bike, don't just blindly ignore this stuff it won't mend itself and will end up costing you both time and money it the end.

If your bike has already told you, not once but three times you've got a problem and all you do is replace the fuse 9weakest part of the circuit for that very reason) don't be surprised to have it come back to bite you.

Preaching over, I'll put away my soap box now. :rant:

not just aimed at you squirrel_hunter as I deal with this type of thing all to regularly.

Cheers Mark.

Rictus I totally agree with your post. However I would like to make it clear that I understood that the bike was trying to tell me something, but the last time it blew its main fuse, (almost a year ago (http://forums.sv650.org/viewtopic.php?t=32062)) I could not find any fault and the bike continued to work without incident (electrical) for some time.

So when it went on Wednesday, I just put it down to one of those things. But when it went coming into work I knew something was wrong. So my plan was to ride home and start checking all the connections once its in the garage.

Like I said originally I thought I had taken enough precautions against this happening but turns out it wasn't enough. Modification appears to be the answer...
