It is the stator coil that has windings and needs to be rewinded with thicker wires.

We replace the AC/DC combo RR unit with a DC-only RR unit. Normal charging rate for the stock electrical system is about 1A. We need about 4-5 times of that.

^^^ thnx for the info... also pls give some info regarding the gauges of wire.....

@Puneet - Appreciate your patience in helping me understand basics. Thanks.

Looks like this is a good option then than BiXenon isn't it?

Fantastic info; this helps me a lot in understanding. Tks.

Hmmm...not sure how to check this. May be rev & check the output from RR unit using a multimeter?

Pardon me, if this sounds silly because I'm talking only from a logical perspective & not actual Physics.

Lets say, I take a separate battery of 8 amps exclusively for my HID setup. Keep the existing wiring on undisturbed; wind coil in the existing generator so that it charges the existing 5amps or 2.5 amps battery as well as the new 8 amps battery.

Take another line from the generator (wound up) & feed into another RR unit that makes 4 amps at 4K RPM for charging the 8 amps battery & use it for HID.

What're the flaws in the above approach?

PS - If I've not stated anything clear, pls point out, I'll break down further.

EDIT
Buddy isn't it Watts/Volts = Amps?

How do you account for these type of coils w.r.t charging, relay & points?

oh my god !!!!

guys why don't you search some threads initially or at-least GOOGLE before posting up every single question..

now let me clear up 1 part..
DC CONVERSION for AC bikes.

okay..
first let me tell you, HID when switched on, does consume more current, but DEFINITELY not 8amps or 10amps as someone said.

the basic is that AMPS means Current.
so the calculation is 35w / 12volts = Current (amps)
so in general a 35w hid/halo/anything will consume 12v and require totally 2.91 amps (stabilized).
before it goes to stabilized stage it requires MAX upto 4 amps. goes down pretty quick, so even a 5 amp battery is sufficient for a single HID.


now lets come to VERY BASICS of coil rewinding and APE RR.

see there's 1 thing called as coil.
it CHARGES your Battery.
it looks like this ---


so generally out of these 7 poles, where copper wire is winded, 3 are for HEADLIGHT (which is on AC), while 4 are for CHARGING the battery.
which in even simpler terms means that 3 of the poles will provide current to the headlight bulb, 4 will provide current to the battery to CHARGING.

so when we talk about DC, we pull up all the current from the BATTERY itself.
so initially your headlight had a different source, now your battery is that source, so it will DISCHARGE Faster, no matter how much amps has the factory provided.
to overcome this we do COIL REWINDING.

what we do it USE all the 7 poles for CHARGING ITSELF.
so those 3 poles which go unused otherwise are used to charge the battery..

to do this you need to take a SINGLE WIRE, rewind it across all 7 poles and then give output to ape rr directly with no other contact.

got it ??

now your battery is getting almost double charge.
the reason we use ape rr particularly is because it NEVER OVERCHARGES the battery.
if battery is fully charged, it won't even provide 1 amp extra.

my bike's ape rr provides 0.89 amps at 12k rpm if the battery is fully charged.
but when needed, the same ape rr provides 13 amps at 12k rpm, when battery is dead, also when both of my HID's is ON.


got it ?

For Pulsars, 19 AWG works best.

There is simply not enough space to wind a seperate coil for the 8A battery, and the current coil can only generate as much as it is doing currently.

And, I would strongly recommend you not to go for dual RR unit + batts. It can go kaput easily and would be a mess to maintain too, plus there is no advantage in it.

Thanks Abhijeeth;
Suddenly its all making sense to me; let me share what I was thinking until now. I was considering an option for HID setup with Rx. Now its more than evident as why it can't be fixed; may be possible, only if the coil is changed like the ones on the modern motorcycles.

And this is no easy job since the coil is mounted on the crankshaft. Either one has to make a custom stator plate which IMO will also cause the entire wiring to be customized in turn; which clearly means - BIG MESS!!!

But I'm immensefully Thankful to people here for helping me understand the basics. May be I'll try doing the setup on my WagonR, it should be possible. The car has lots of potential as it carries around a 35amps battery

Doesn't matter where it is mounted! Have you seen the coil? Was it wounded to the full with no extra space? If not, you can always rewind. BTW, I have heard of RX100s with 100W bulbs. Seems possible to me.

what's wrong ??

i have posted on page 3, how come 2 of my posts get displayed here on page 4, that too one of it which was incomplete ??

Well, Rx100's with 90/100 kit requires a different generator altogether. See my first coil plate that has 3 coils; that one is capable of supporting 90/100. Do you think that one can be used? I've a different RR unit for that coil.

The next one you see with a single coil is a stock 12V for Rx that's capable of supporting 35/35 which is presently being used.

However you see, the stock is capable of charging only a 2.5amp battery & the 90/100 is capable of charging only a 5amp battery, while a Projector/HID setup or a BiXenon requires a 8amp battery, unless it really needs 2.9 or 3amps battery as NanoTech says. In that case, I'm running a risk of loosing the charge on the battery; and one of my reason to state for a separate battery & RR unit exclusively for HID was this reason.

You made a double post dear; one with the incorrect V*W calculation & other with W/V calculation.

Nope, nothing like that, as long as the coil gives out about 4A (not the same as supporting a 4A battery, that will need only about .5A) , it will work fine. Battery does not really matter much.

The 100/90 line in the first coil is a separate AC line? And there is a separate DC line for the battery? In that case 100/90 line will be good enough both for the battery as well as the HID. We can leave out the other DC line.

Do you have some more detailed pics of the 1st coil? Wanted to see how many coils are winded on it.

I'm getting confused here!!! The first generator I know supports 5A battery, but a group here says a 8A battery is required for HID, another says 3A. So unless these are sorted out, dumb people like me will stay in confused booth!!!

Frankly speaking, no clue at all. I was under the impression that to utilize more space & wind more coils, there're 3 of them compared to a single. So now it looks like its a wrong theory as there're some coils meant for AC & some for DC. Looks like I've got my basics wrong here.

Not sure

There're 3 coils only. Damn sure. I'll try to take a pic of it & post here.

@ abhi..

dude, are you mentioning that use 2 rr's, one for charging phase, and the other for the AC output of lighting phase, to send it for charging phase to battery again ??
won't it be a pain in the Bum ??
why not do a simple process of making it single phase, the amps generated will also be more..

@ aargee

don't get confused mate..
see Hid runs of at-least 4 amps...
no matter how much amps your battery is of, Hid will need 4 to start.
so if you have a 2.5 amp battery, and if your bike when ON can provide say 4 amps somehow in idling (which is possible but extremely difficult) then Hid will light up instantly, without any issues..

but if your battery is say 9 amps, or even 5 amps, it won't need the engine to be on to start, so battery drain will also be slower.
hence its recommended to stay with a battery giving 5 amps and above..


@all



if we look at the Second picture with only 1 pole
i doubt this coil will provide necessary 4 amps or above..
it comes in 100cc bikes, abhi are you SURE that RX100 can support a 100w bulb??

in a 100w bulb is on AC it might as if amps are lower, bulb won't glow at full intensity, but a 100w bulb on DC will need good amount of current all the time which i really don't thing this coil can support


regarding the first coil, i believe it can provide 4 amps if properly winded, as my stator can provide 12 Amps....
the poles are bigger, it is very much possible...

^^ No, I am suggesting him to use 1 RR unit only!

oops, my bad.
i thought you STRONGLY SUGGESTED, instead of STRONGLY NOT SUGGEST...

Ok, you're giving me some hope now

That's very clear; I'm getting a hang now.

Yup; got the point.

No it isn't; the second one is a stock Rx100 that is sufficient to charge a 2.5a battery.

Are you asking me? In that case, the first one on the pic is a stator plate from RDD that support 90/100 bulb & they also recommend using 5a battery. Which means, their coil is capable of supplying 5a charge to it. How do you see this? Would that be sufficient to support a HID when the motorcycle is idle/running?

You mean the first one or the second one?

I'm not sure on the amps, but I can VOUCH it support 90/100 bulb.
