YELLOW WIRE WITH A BLUE STRIPE

Any ideas on what the yellow wire with a small blue stripe goes to....I found one taped off and rolled into a ball in the wiring harness. My battery keeps going dead when riding ( I am getting a steady currrent ( If i have 12.2 volts and kick start the bike it will hold at 12.2 at idle but if rev up it stays the same. If I turn on the headlight it drops to 8.4 etc.) I am looking for the culprit. By the way the bike is 2001 FX470e.If i let it sit for a week I have maybe 9.1 to 9.3 volts.

Thanks
Heath

I do not have any knowledge of the older models.

Check the wiring schematic, but it sounds like a CDI to ground lead used for kill switches and on some models for an ignition key disconnect. My 06 schematic shows two of these leads - maybe you have found a spare one?

Cheers

From the schematics, the only one like that connects to the start button, and from what I see it is specific to the Hi/Lo mapping thing. The schematics is not always right, I have seen wires with the wrong color. So how long is that wire and where does it go?

Otherwise, you have a drain somewhere, or the stator is not giving mucho voltage, which would not surprising from a SEM unit. You can have it rewound by our friend Sparks. It may be the sign of a dying stator.

Since you have an FX, I suppose you do not have a headlight, which would drain a few extra volts (I am about to add a switch to prevent that drain during day time, except for when I am in hi beam, so I can give a quick "see me?" flicker).

I did put a headlight and tail light so that I could tag the Berg. The wire is apx 18" long and ties in on the backbone just above the carb on the left side. It has a small rectangular plastic clip on the end of the wire. Is the SEM something that I should upgrade?
I did put a 3 position switch to the headlight ( on off and hi) that didnt help me any.

With all the lighting equipment hooked up, it is not uncommon to see a drain and the voltage go down. You can have the SEM rewound, everybody swears by it. You can also add a switch, as I am about to do, to prevent the headlight from operating when you are dirt riding, then once on the road, turn it back on (daytime running lights are a must on a the road). One of these days I will send my SEM To Spain.

Also did you connect on the AC, or the DC? Does the light go down in intensity when the bike is idling?

Hi bhbzx7,

You generally find that most electrical problem to do with lighting and charging are down to a bad connection some where usually a bad earth.
The Blue wire is ground both Yellows are common to each other one Yellow feeds the regulator rectifier for charing the battery and the other feeds the regulator for the lights.
If your battery is dropping to such a low voltage then I suggest it could be knackered, it should charge at around 14v same as for the lighting should be around 14vac off idle.
But if your model wasn´t fitted with lights then the wire you have found will be to do with the AC regulator side.
Let us all know how you get on.

Regards

Sparks.
