VFR Discussion Group -> Electrical Problem

I have a problem ref. the FI light on my 1999 VFR 800. When I put on the dipped beam the FI indicator lights up. If I then pull the front brake lever and use the pass light switch all at the same time the engine cuts out. The FI light does not flash when the engine is started and the side stand left down. If I am riding on the road with the dipped beam on the FI light is continuously on , if I switch to side lights only the FI goes out. At the weekend the bike cut out on me 3 times while running with all the lights out at constant speeds between 90 - 100 MPH but would run ok at 70 MPH or below ( it restarts after a few minutes and pulls strongly throughout the rev. range up to the rev. limiter in lower gears ).
A while back my Regulator/ Rectifier pack up which was replaced with a second hand Regulator/ Rectifier and a new Battery. The second hand Regulator/ Rectifier was from a 900 Honda , this seamed to cure the problem but the FI light started to come on occasionally after 200 miles. This Regulator/ Rectifier was then replaced with a new pattern unit for the VFR 800 , which brings me to where I am now.
If anyone has any ideas what is wrong I would be most greatfull to hear from them.

Thanks

What are these? dipped beam?? pass light?? and side lights??

Do you mean hi-beam, low-beam and turn signals?

If your replaced Rec/Reg is not mean t for a VFR800 model, would that make a difference?

Dipped beam would be your Low beam
Pass light is the High beam flash switch
Side lights ( Dont know the US equivalent ) but it is the first position that the Low beam switch goes to.
The temporary Regulator/ Rectifier was only fitted as a check to identify if the Regulator/ Rectifier was at fault as we knew this one worked. It produced 1 volt more while running at 5000 rpm 15.8 volts instead of the upper limit off 14.8 volts for the standard unit , dont know if this would produce a fault else where in the system.

Sorry for the difference in terminology between Scottish and American english.

My '99 doesn't have a 'pass switch'. When the bike is started, the low beams are automatically on. When you rock the headlights switch to the other position (there are only two), the lights are on high beam.

Was the VFR-specific reg/rec for the same year bike as yours? Perhaps that's the difference. I suppsoe it's possible that the extra voltage could have melted a couple of wires together, but 1 volt doesn't seem like enough extra power to cause that.

Bizarre, man. It's just strange.

Sounds like a bad relay

For information to anyone out there,after stripping off all the plastics and taking the dash out the PCB looked ok. After checking all connections , relays and earths the last thing I checked (the side stand switch) looks to have been the problem.
I have removed this switch from the bike and thoroughly cleaned it , refitted the switch and so far no other problems.
Done 60 miles last night with no problems so hope this has cured my problems.
