i didn't expect this question to be posted atleast..
should have searched in previous pages or my HID projector help thread, page no 34...

let me answer anyways..
your bike's stator produces current whenever the magnet around it rotates.

when you REVV, with the engine, even the magnet rotates, this helps in producing current.
however whatever current is produced by such method is AC current.

in our bikes the AC current produced by this method ranges from 48v to 100v AC..
this voltage can blast off all the electricals in the bike.

so there's a method to suppress this AC current.

an RR unit is a Rectifier/Regulator unit.
what it does is firstly makes sure that even if the bike produces 40v or 120v, it gives out only 14.5v...

secondly what it does it CONVERTS this AC current to DC..

your battery needs DC voltage to get charged..

so if you look at your stock RR unit, it has 2 phase, i.e

• it keeps AC current (given to the headlight) below 14.5v, this is done by 1 phase out of 2
• it converts the remaining current to DC and gives it to the battery, again suppressing it to 14.5v (done by second phase)

now what you will do is BUY a SINGLE phase RR aka APE RR..

it will only do 1 thing, i.e convert ALL the AC current to DC, limit it until 14.5v and provide it to the battery..

got it ???

now if you ask about rewinding, rewinding is a process in which the stator is winded with copper wire to give MORE current as we need better charging to run HIDs..

this is my re-winded coil (sorry for image quality)



so its evident from the pictures that the COPPER thing is much more in the RE-WINDED coil, as well as the wire is fatter, so its much better winded.

so again i repeat..

what we are doing is making our charging system better by generating more current with the help of re-winding, and that RR, is to regulate/rectify all the AC current produced to DC and send it to battery .....


i hope i don't need to clarify any more doubts...

and this is how the stock coil looks like (ignore the circles)

good to see the detaild ans from you nano.you are emerging as the best helping hand for xbhpians here.
i really like your simple step by step method of explanation,heck you will be a good teacher,do you know that,AND I AM NOT K+JOKIN OR KIDDIN WITH YOU,.

Hi Guys,

Can anyone provide me contact of machanic who can do HID set-up in Mumbai or Pune.

P.S. I hv got HH Hunk.

My fellow Xbhpians,
I need some expert guidance on installing an HID kit/Xenon on my Yamaha Fazer.
A brief background on the bike. The current electrical system is 12V35W/35W+35W. The feature with the Fazer is that though it had two bulbs independent, at any given point in time only one would work. (The right buld works on low beam and the left bulb works on high beam)To enable both the bulbs I had changed the battery to the R15 battery to support 35+35W.Even after doing that I am not satisfied with the quality of light avaliable especially on the highway at night when its raining and worst is when you have a vehicle coming in the opposite direction with their high beam on.
I was being offered the angel eye with Xenon for a premium of 16K with a 1year warrenty and would have to install an additional battery charger (Rs 500) to cope with draining of the battery, however I do not think it would justify the cause and would just be a pocket ripper.I had gone though the tread and was utterly confused (as I dont know head nor tail of electricals) with what would work best for me. Can you please advice on a viable solution?
Hope to hear from you soon.
Thanks for looking into this
Cheers!!

hey guys, can anybody help , since I have installed Bi-xenon projectors but then my 35 HID 6000k is darning so much battery that the FI signal on the console flashes notifying the battery drain, is there any solution to this ? should I get a brand new battery as I have completed my 2 happy years of ownership. And more off I dont want to go for rewinding as a solution to this. Since the stock halogens are of 35W why does a 35W HID drain the battery in a matter of just 5-7 MIN please give me some insight ....

I guess ur ride is a R15 from ur avtar. Its got a strong electricals to support 2X35W halogens at a time. Check the battery condition as u said its 2 yr old, if not, check the RR pumping rate to the batt. A 35W HID should not make any issues in normal conditions. How about the stock bulbs? Are they giving good backup?

Dear Doc,Abhi,Sajan, Nano.
Rewinding done on my pulsar 200. Installed APE rr unit. Everything done by NANO. I am very lucky to have him in my city. i was just standing beside him and was looking at his job.
Thanks a ton NANO.

The problem i am facing is i cant get the headlamps converted to DC. BCU is not allowing me to do so. How do i bypass BCU. As for now mechanic has installed an extra switch to on/off bulb on DC.
PLs help.

Single HID is ok, but R15 supports twin HID too in normal city traffic?
