Very interesting.
-
When I am through it will advance to a "black belt". Hahaha
-
very innovative :D
-
Very cool! So those lights only work when your riding?
-
No, I will have a battery. Of course the batteries will only charge when i am in motion.

haha nice!
More pics / description Grandmaster!

Most will know what is driving this modification but, this is on my "hybrid" build and it is a "desert theme" so I wanted the larger lights, but also use my CR ignition. Did not want to modify and risk reliability or performance of the CR and since I have not found a better idea, thought I would give this a try. Confident it will work, looks kind a "FUNKY" but hey, It is a hybrid bike so we will see. Hahahahaha

It is a Kubota grass hopper alternator. Puts out about 20 amps max at 14 volts. (Ebay 59.00). Fabricated an adjustable mounting bracket. Bolts to the swing arm.It will put out an average of 160- 190 watts. Main lights are 100 w total HID will add some LED also. This lighting is mainly for show even though they will be functional. Not planning on spotlighting deer n running em down. HAHAHAHa

I was gonna mention trying LED's. Those will pull way more AMPs.
-
The bracket is stainless, I will make stainless spacers when I get the all the alignment true. I will fab a stainless guard with some sort of sealing device to protect the armature and stator from the elements. Just tinkering.
-
The HID ballast will charge when they come on and the battery should handle that in rush current load, then i believe the running amperage should be around 5 amps each if my research is correct. We will see, like I said, Tinkering

Please explain? I may have missed something in my research.

Here is just a quick article on it. Not being a jerk. Just trying to help ya out. I think this project is pretty bad ass. I just picked up a small led fron and rear led red light an just going to run a LI-PO RC battery. It wont be for long rides. Just to get to the hill and back on my duner really.

I do not think you are being a jerk at all. I know that LED lighting consumes allot less power and is more efficient. The formulas for electricity calculation are uniform so doing the math is simple. I believe the start up in rush current is the deciding factor on how much total current supply I need. I will size my battery accordingly.
I will not be spotlighting anything so most likely the light will only be run when I am riding and most likely as not both will not be on at the same time, that is why one is a spot and one is a flood. Its how the desert riders set theirs up i believe, and that is the theme of my build.
Thanks for your input!

Just a quote from the article you referenced
The Future Of Leds
Light emitting diodes may well be the real future of multi-purpose and off-road lighting. For applications where the light is made "to be seen" (tail lights, brake lights, etc.) they offer excellent visibility in signal colors. But, in applications where they are used to "see" they can't yet match the sheer illumination power of HID lights.

That article is from 2010. I have LED's on my truck, my buddy has them on his Rzr, I have ridden other atv's with them. They work just as well as HID's now.
True, when they first came out the housing didn't project the light as well. Now they do.
-
You are absolutely correct!
They have made great advances in LED tech. I wanted to use a one bulb design in each light that I could afford and give me the light housing dimensions i was looking for. These HID's meet what I'm trying to accomplish. Like i said before I am trying to get a certain look with my build. But I want everything to be functional. Does not have to be efficient or even practical.
Thanks again!
-
That article is from 2010. I have LED's on my truck,....
Are they just one LED per light or multiple?
Appreciate it!
-
I have these in the stock fog location on a F250. I'll take some pics tonight for you. They are in a spot configuration. I got a cheaper(Chinese) knockoff for the ATV in a fog pattern.

On a side note. do you have a lathe or easy access to one?
-
Thanks! Yes I have access to a lathe. That is how i modified the pulley on the axle nut.
-
Here are some pics for reference. The fence is probably 500ft away. The one is with the brights on and the other is with the LEDs.

Leds
-
I researched many lights. Led has come a long way no doubt. Thanks for the Pics as well as the input. It is appreciated.
-
One note here also. If I could have found a comparable alternator that had smaller dimensions. I would have used it. Of course the the ac voltage will be run through a regulator rectifier and converted to dc.
Also, no more than I will be using the lights I could have used just a battery but I just wanted to try something different.
-
I like your design. Another thought that I had but haven't tinkered enough yet to get around to it was to mount the alternator to the swing arm but in line with the chain. I was thinking of using a toothed sprocket for the alternator pulley and a spring to apply tension. Basically using the chain as the belt.
I have a friend with a crf 450 hybrid. He had the stator re-wrapped and it can now support 250 watt's. I think he used Ricky Stator.
On my R I run a Ricky Stator high output and I prefer it over the CR ignition. (Mainly because I ride a lot at night.) The performance gain just wasn't a fair trade-off.
-
Originally I was going to run it off of the chain. Once I started studying out the mechanics and seeing that i would have to apply tension to allow for the pivot arch of the swing arm, I decided to go this route because I was concerned that the chain method would be high maintenance. At my age, I don't need anything "HIGH MAINTENANCE".

-
This is cool. Are you worried about the tension from the belt "adjusting" the axle nut while it's turning?
-
The OEM lock nut is locked against the pulley and the pulley is recessed over the primary nut housing. The pulley acts as a spacer so there is no loss of locking force of to the lock nut. I do have a concern about the pulley being aluminium but it is aircraft grade. If i need to I will make the primary nut a squeeze type lock. Just experimenting now. Being left hand threaded may help keep it tight.
I appreciate your input.

Little update here on this project.
Since i now have the bike up and running that this is on, I tried it out. It will work and indeed put out the voltage i need (13V). Yea!!! but... I have to hit 76 miles per hr before the flux capacitor will kick in. HAHAHA (Just a joke there). in reality about 40 mph.
I need to make a bigger pulley for the drive side about 8 inches. I have sourced the billet aluminum I need and my machinist will put it on the "lathe a runi " and fix me up. Hopefully i will have it completed by the OCT ride at ST JOE.
I will update when I make more progress or if i get a letter saying I am being sued by DeLorean or DOC Brown.
-
Interesting. Thinking outside the box. I like
-
I wouldn't worry about it, Doc is a good guy. What is St Joe?
-
ST Joe Park in MO. Ride planned there on the 8-10 next month
-
Little update. Made a larger Dia pulley and installed the matching Kubota regulator/rectifier and I get 13.5 volts at about 25 mph. I will put a sealed battery and make a wiring harness and I should be good to go. Just trying to do something unusual. Like was suggested, I may give the LED a try. I can buy H4 socket Led bulbs to put in my existing light choice.

The light bar came with an old set of Dick Cepeck lights. I may powder coat the cans and use them. They also take the H4.
I made the light bar so it could be installed/removed in a few min. I will be able to put the white Maire head light on easy.

My hats off to you [MENTION=123]mrtwidster1[/MENTION] - this is slick!
-
^^^^^ Thanks
-
Battery and voltage reg operational. Lights work. Maintains 12.5 volt charge to battery. I will put the electrical through some testing this spring. Once it is proven dependable I will make a proper wiring harness.
(http://i544.photobucket.com/albums/hh331/mrtwidster1/F39A6B4F-99BA-4A71-9F32-A3E7C77856E2_zpss5wnsl1s.jpg)

You have created something very impressive mrtwidster1. You have a creative mind. I'm looking forward to a tried and tested review B/c I may have interest in being a customer if you decide to sell a package to make this work.
-
I will update after i have used it awhile. If it proves dependable then I will do a full spec write up. Thanks for the interest.

One spot one flood. I will put h4 led bulbs in eventually and try them.
