I have had my bike for about 2 months now. I have noticed this twice recently.

I will be crusiing along and I will notice the tach drop to zero and jump up, it will do this alot at lower RPMS (<4000) but tonight it also happened at higher RPMS <7000 occansionally it would stay off comlpetely for a few minutes. Also the headlight would be extremly dim, as would be the dashlights.

Not sure what the problem is. I just had it worked on mechanically and I had a full tank of gas (not sure if that would matter) my battery is just over 2 months old.

I can only think it might be the alternater is going bad becuase I am not puting any unessacary load on it and I am not going below 4000 RPM frequently.

Also it runs perfect all the time.


And when Idleing the electrical problems seems to go away completely.

I am completly lost with this.

Any idea?

There is no alternator 

Check your ground connections and battery connections  What year is your GS? only newer models have an elctric tach

What year?

89-02 have mechanical tachs - lube the cable and make sure it is tight.
04+ have electrical tachs - look for loose, bad or corroded connections.

How do you check the ground connection?

maybe that my problem, I think there are parts there really aren't. I have an '04.

Thanks

Fallow the ground wire from the battery to where it ends.


If you live in a humid area or high rain fall area,you may have moister an corrosion in the wiring plugs.
