hello, my fe400 2002. has no voltage- regulator. Of the two wire yellow, 1 connected to regulator / Rectifier, yellow and the other not connected anywhere. Is that correct?
Just load 11.8v. to connect the lights 20 minutes after the battery is dead .....
 
Download a copy of the 2002 owners manual here. In the back are wiring diagrams. It looks like the FC & FX do not use the second winding, but then they don't have lights either? Have yours been fitted aftermarket?

:microwave: PS. Introduce yourself with a bit if info about yourself before too many other posts, otherwise you will likely get introduced to Taffy!
 
I regret not having made, but my English is poor. I am in Spain and I have a Husa (enduro) FE400 2002, purchased in 2008. I have the wiring diagrams and the diagrams shown carrying a yellow regulator, but my bike has no regulator. The other yellow yes connects to if rectificator / regulator
 
the reg/rect is used to provide about 13v dc voltage to keep the battery charged. you can get an aftermarket voltage regulator for about $25 us. it will be used to keep the lights at about 12-16v ac.
disconnect your lights from the reg/rect and measure the voltage. it should be about 12-15v dc, and almost no ac. if it is wrong, make sure your ground connections, including the bolt that holds it on, is clean.
 
Your bike most definately has a regulator, otherwise you'd be measuring voltages much higher than 11-12v. Also, if you are measuring DC, then your rectifier is working as well. Depending on your power needs, you can choose to connect one, or both yellow wires.
 
view???

Do all your lights, blinkers, horn etc work?
On an OEM setup your headlight, brake and tail light should only work when the engine runs and be AC (regulator only).
The blinkers, starter and horn should be on the other DC (regulator/rectifier) circuit that also charges the battery.
If everything works with only 1 DC circuit then you or someone has prolly bridged the 2 circuits together and if you've only got 1 alternator winding connected then you only have half the power - about 70w from memory.
I don't think you can simply bridge the 2 alternator windings onto the reg/rectifier unless it can handle the full power.
Someone else may be able to advise here.
 
Trail Tech sells a Regulator / Rectifier that is rated at 150 watts.

Take a look at the 2003 wiring diagram as this model ran 100% DC power and does not have a seperate regulator for the lights.

If you are just going to run the stock lamps then it would probably be easiest to buy the missing / removed regulator and put it back the way it came from the factory.
 
Are you sure it is a 2002 model? The 2003 only has a single regulator/rectifier and the entire electrical system runs off DC - ie the battery.

Was it sold in 2002 but is actually designated a 2003 model? Others here should know better how to identify it positively.

If this is the case, the reg/rect unit is a fairly standard 3 phase type unit you would see on pretty much any Jap bike - even though the stator isn't. All three wires from the stator - both yellows and the blue - connect to the three yellow wires on the reg/rect. The order should not matter, provided that all of the diodes in the rectifier section of the unit are OK.
 
yes, sure is 2002. I buy 2008.
1 yellow is disconnect offline.
regulator/rectifier is of 4 pins
a drawing picture of diagram, would help me
 
nobody ever listens to the old guy ](*,)
 
just gave you that link as a reference. do a web search on motorcycle voltage regulator and see who does ship to you. another alternative is to get a used one from a kickstart dirt bike with lights. i used a suzuki dr unit on my 98 for years.
