F.I. Light turns on at high rpms and turns on and off with the front/rear brake...

Hey Guys,

I have problems with my FI light coming on before... today I was riding around with my girlfriend and the f.i. light started coming on at any speed above 50 (bright red) but would go on and off if I clicked the brakes (either front or rear)...

what gives?

That's kinda weird. Your bike may be trying to tell you something. You need to find a shop manual and look for fault codes in the self diagnostics...or take it to a dealer and ask what they would charge to run through the self diagnostics...it only takes a very few minutes so the charge for JUST THAT should be minimal.

 

i shorted the connector today and tried to pull codes but none were stored...

bike runs fine btw...

Hmm...my next move would be to remove bodywork and inspect the wiring...paying particular attention to the main grounding wires where they bolt on the frame/engine.

 

If the light reacts to other electrical loads its an earth fault. Check the earth cluster block just forward of the RR.

 

similar trouble

I had similar symptoms on my '01 that eventually left me stranded 100 miles from home. i read the posting here and elsewhere and followed the usual parts relacement(rr, stator, added rr fan) with no luck. my problem would coincide with any amp draw irregularities: blinker, rad fan, etc. Eventually, I replaced my wiring harness and the problem went away. The harnes was like 275.00 US and took 1+ days to complete.I checked but never found any evidence of trouble with grounding, loose wires, faulty terminals, etc. Was the harness bad or weak? did I treat the symptoms without finding the real problem? I guess only time will tell. best of luck amigo.

 

Mikeym, you beat to the punch with posting about this as I just ran into a similar problem on a ride three days ago and then again yesterday. My FI light would glow dim when turning on the left turn signal then extinguish again, it never quite completely illuminated and the bike never missed a beat. Hmmmm! Seems we may share the same gremlin.

I will let you know if I find anything that may help your situation.

Thanks for the suggestions guys.

Check the above post. You may have the problem I had

 

Mikeym, and others,

Did you check out the reply that I posted on your query on VFRD forum. I managed to post a picture of the suspect earth block. here is the picture again.

I had two problems, the contacts were dirty and corroded, plus one wire was just about broken. You can see where I re-soldered it.

Since then I have done away with the block completly, conected the wires to eylet conectors (about 4 wires per conector) then bolted them all together, with an extra with to earth on the chassis. Since doing that I havent had any more problems.

 

Useful posts...the ground block that hatzian describes has been an issue on other models. If I remember correctly there is even a wire harness recall on certain models of ST1300's pertaining to this very ground block (seems I remember cussing at one some time in the past...it's buried behind the throttle bodies on the ST). The block is elecrical taped so you must cut the tape to inspect it.

Luckily Captain John found this problem. It gets even trickier if the problem is a loose fitting pin INSIDE the connector. Sometimes you can find this if you lightly pull on the wires at the component in question. Also, Honda has a 'fit' tool available to check the fit on the various types of pins used in their connectors. Simply insert in the female terminal in question, hold the connector upside down and it should be tight enough not to fall out and hit the ground.

I looked at the wiring diagram for this model and it's interesting to note the various 'idiot' lights in the gauge assembly share a common ground. I could imagine the problem being in the gauge cluster itself, although I think these other suggestions are worth investigating first. A skillful tech who knows how to check voltage drop may be able to locate this problem with a multimeter by going through the ground circuits and looking for one that's consuming excessive voltage...or, it may be possible to disconnect various compontents and look for excessive resistance on grounds through the harness itself.
