I have a 2002 FXD and plan to add a sidecar. I would also like to add auxiliary lighting but can't find a spec for the stator/regulator current output. Don't want to exceed the rating!

Has anybody seen a current rating for the FXD?

Thanks!

 

For anybody that's interested, I found current ratings for the stator in the testing procedures - 22A minimum @ 1000 RPM. Assuming 75% for a continuous rating, that would be about 16.5A continuous.

 

I run aux lights on my '03 FXD.

Generally speaking, most H-D models have a 32 AMP electrical system.
Here's how to calculate your power consumption:

volt X amp = watt
so
watt / V = amp
for the passing lights: 110 / 12 = 9.1 amp

Headlight takes 55 watt = 4.6 amp
Running lights take 5 watt each = 0.8 amp
Directional lights take 21 watt each = 3.5 amp
Brake light takes 21 watt = 1.75 amp
Rear light takes 5 watt = 0.42 amp
Etc.

With a 32 amp system you will be good.

Here's a passing lights wiring diagram.
Some options:
1. To run passing lights independently: splice battery + or ignition switch powered 12 v wire to switch in diagram
2. To run passing lights with low beam: splice low beam 12 v feed wire to switch in diagram
3. To run passing lights with high beam: splice high beam 12 v feed wire to switch in diagram

 

Thanks 3Rider!

 

I am not very knowledgeable about electrical issues but couldn't you also use LED lights to lessen the load?

 

Not to hijack this thread, but having to pull my inner primary, after pulling clutch and compensator sprocket, noticed my rotor has stamped "High Output". If I remember my 05 FXDI has a 32 amp setup. Can I assume that the previous owner upgraded the charging system? or all 32 amp systems are considered HO.

 

In general, yes - LED lights will lessen the load. However, I live in deer country and had a pickup truck written off when one BIG friggin buck jumped out in front of me. I now run a set of powerful "ditch lights" on my truck so I can see those buggers coming before they can get in my way. I plan the same kind of lights for the Harley and sidecar. It would be a mess to hit an 800 pound buck on a bike!

Ain't that the truth!

 

Yes, more light is better in my opinion too. And with the same concern in mind. My point is that if you swap out the current lights for LED lights, you can add many, many more lights, especially if they are LED too, without being concerned that you are over taxing the system.

 

I have never seen a LED spot light with the intensity and the range of the incandescent off-road lights that I have on my truck. With deer, it is about projecting light a LONG way ahead in the ditch. LED lights have their role but they aren't up to aircraft landing lights yet
