2001 XR400 Wiring Question

OK, I've researched this project and I think I have it right but before I start I wanted to run it by you Wiring GURU's.

I have a stock 2001 XR400R. Did I mention it was stock. I want to make it a little more street legal compliant by adding a control switch and front and rear LED blinkers. So i'll have incandescent headlight and tail light with LED front and rear blinkers. I plan to wire-in a resistor wires prior to each blinker (4 total). Here's my parts...

1. Acerbis Headlight http://www.motorcycl...-Headlight.aspx

2. H.D.B. front blinkers http://www.highwaydi...ef=turn_signals

3. Rear Blinkers http://doctorenduro....ush_mount_smoke

4. Baja Designs Control Switch http://www.motorcycl...&WT.MC_ID=10010

5. DRC Resistor Wire http://www.drcproduc...5-90/index.html


Route will be....Stator.....to CDI.....To AC Reg.......to Control Switch....then out to everything individually. Straight to the headlight.......straight to the tail light..........Resister Wire then to front blinker (X2)......Resistor Wire then to rear blinker (X2). I created a diagram and hopfully it attaches.

Does this look right to everyone???????? Thanks in advance

Stock system is AC, the LED lighting requires a DC system. You'll need a voltage reg/rectifier and a battery or capacitor. Best method is to add windings to the stock stator and run a DC system seperate from the stock AC system.

That's what what I was told the resistors would do

Resistors won't convert AC current to DC.

great, why would someone suggest that. What do resistor wires do?

Resistors cut Voltage by adding...


wait for it...


resistance to a circuit. A common use for resistors in a Direct Current LED turn signal circuit would be to make a regular-ol' thermal turn-signal flasher work (tick-tock... tick-tock...)

Without enough resistance in an LED turn signal circuit (using an older thermal flasher), the signals come on, but won't flash.

You can make it easy on yourself and simply install an electronic flasher specifically made for low-resistance LED lights. NAPA and better parts stores have them in stock, just make sure it's for LED's.


Alternating Current does just that... alternates direction, back-and-forth 60 times a second. In order to convert Alternating Current to Direct Current (Rectifying), you need a number of Diodes (not resistors) working in parallel.

Diodes are like one-way check valves for electricity. Flowing through a Diode, current can flow only one direction, but not the other. Ta-da! Direct Current (one-way only). This is the Rectifier portion of a Regulator / Rectifier. The Regulator limits the output Voltage to 12.5 to 14.7 or so, while the Rectifier converts AC to DC.

Baja Designs and others sell a kit that includes nearly everything needed to convert an XR4 over to usable DC (for lights, battery, GPS power, etc.)

Because they are clueless Seriously though, they are referring to adding LED blinkers to an existing DC system, not what you have on the XR4.

Good explanation Stretch (except the 60 cycles per sec, on a MC the cycle is RPM dependant)

Bigdog, you're trying to pull more from the system than it was ever designed to produce. In order to have blinkers that actually work (and a decent headlight) you'll need more power from the stator. 3 choices for that, install a battery that you periodically charge. Rewind the stator for more power or install a higher output stator. THe system on the 400 was designed to run a tiny headlight and taillight, it's AC which doesn't play well with DC componets like LEDs. I've added DC power to a few XRs and to get what you want you'll need a stator mod or replacment, a voltage reg/rect and a small battery or capacitor.

If you want to buy the parts, figure $240 bucks, stator is about $150, reg/rect is about $50 and the cap is about $30 bucks. The stators come with two 100W outputs, wire one to the existing AC system and leave that alone. Wire the other to the reg/rect inputs, the outputs go to the small battery or cap and all your DC runs off that. Both systems must be seperate and cannot share grounds. This is done by running the DC's grounds back to the battery or cap's (-) terminal. This method will give you 100W ac for the bike's existing electrical system (plenty left over there) and 100W for the DC stuff which is plenty. If you use a cap, expect the DC stuff to be a little flakey at idle where the system's output is very low, with a battery, it takes over at that point and will provide power to run the DC normally (within reason).

Thanks for the info guys. I hate 1/2 assing anything so I guess I've got another "project" thats taken on legs....

Do you guys know where people have been installing batteries ect ect on an XR400?

What size battery would I need?

If i replace the stator are there replacements that put out to much voltage. I've seen dual 100 watt and dual 125 watt stators.

I just installed a lead acid 2.3A battery under the seat. It fit perfectly in between the frame tubes and sits above the air box. An nimh AA pack fits a little better but I got a good deal on the lead acid battery from Batteries Plus.

I skipped the battery and went with a cap, it won't run your blinkers though.



A 1.2A SLA alarm battery will fit in the same area as the cap. I like those batteries because they are sealed and cost about $18.00, I've used one on an XR650R for a few years. You can see the location of the Reg/rect, it's a Rickey stator model, fits that location like it's made for it.

What size battery to you guys recommend? The smallest I can get away with.
