i had a problem like this before, and it turned out to be a bare wire that had rubbed into contact with ground. i imagine that's what it will turn out to be this time, but this time the circuit is much bigger and it's a lot more ground to cover.
my "symptoms": this morning my tach/speedo/temp console went out, along with my headlights. turn signals still work. bike still runs.
i have no electronic accessories.
i accessed the fuse box and discovered that a 10 amp fuse had blown out. i replaced it and headed back out onto the road. about 10 miles later, it blew again.
upon reviewing my wiring diagram i notice that the headlight are supposed to be on a 20A fuse, though i've never changed any of the fuses in the fuse box before, so i there's no reason it should be any different than the factory (unless the previous owner had switched down to the 10A for no apparent reason).
anyways, looking for any thoughts you blokes might have.
In another thread a couple of us had our headlights go out during miscellaneous electrical woes... have you checked for that rare loose connecting pin in the main wiring harness?
Had the exact same thing happen to me when I first bought my bike. It was still under warranty, so I took it in to the dealer and they first diagnosed it as a blown fuse, but after I kept bringing it back with blown fuses, they called Honda headquarters. Finally diagnosed it as a faulty switch, but I'm not sure whether it was the headlight relay, turn signal, or what, but that was two years ago and since getting it correctly identified, it hasn't happened since.
I have also had this problem with my 03'. I believe it is a wire that is shorting to ground but it only really happens after hitting a bump. sometimes a soft bump, sometimes a hard bump. I guess I'll just have to hunt down the wire then :( . Oh well. Any other suggestions as to the problem? If it is a relay how does one fix that?
2003 nonABS. I installed the same 10A that is supposed to be there unless I miss-read the fuse instructions on the inside of the box. :huh: It is interesting to me that the headlights, display, tach are on a 10A fuse. It seems to me that you would need maybe a 15A or 20A since the headlights alone draw significant current.
But wouldn't replacing a 10A fuse with a 20A defeat the purpose of having the fuse in the first place? :huh: 10A protects against a current surge of that amount. Wouldn't something else get damaged if it surged again and the fuse didn't blow because I replaced it with a 20A??

Has anyone found a soultion to this problem? My 02' just started doing the same thing... 10A fuse in the H/L and instrument lighting circuit keeps blowing. Any sugestions would be appreciated before I start stripping the fairings off to troubleshoot... :thumbsup:
I have this strange feeling that time has jumped forward, not quite a full year. :unsure: I hope Trip has fixed his problem by now, I haven't noticed him posting lately. :D
Just curious, is there a difference between a 2002 and a 2003 as far as the electrical is concerned?? I have a 2003 model but I am using a 2002 service manual for reference. It looks like in the manual the headlights SHOULD be on a 20A fuse but it also shows that the headlights are on their own fuse. I need to double check but I'm pretty sure the fuse box on my 2003 shows the headlight on the same 10A fuse as my meter, indicator, and display. I thought the 2002 and 2003 models were the exact same motorcycle. Am I wrong?? :blink:
My mistake :goofy:. The fuse that is blowing is the 10A Indicator, meter, position, tail, illumination fuse which DOES NOT have the headlights. That is a separate 20A fuse.
I was wondering how to contact HONDA USA and see if they can help me out. I don't have a warranty and I know the dealer is going to charge me an arm and a leg to even try and find the problem which they probably won't since it is intermittant. I'd like to see if HONDA USA already has a solution for this problem.
I'm tracing through the wiring diagram and as far as I can tell there is no relay for the components serviced by this particular fuse. I don't really understand how it could be a faulty relay, but then again I am not very electrically informed. Any ideas?
