Of course, current does matter. But, when you apply a fixed voltage to a battery having a certain fixed charge, it will only take a certain amount of current. If you feed it from a weak coil, or a strong coil does not matter. Only thing is that the coil should supply atleast the minimum current demanded by the battery.

In a simple way, Voltage = Current x Resistance (ohm's law). If the battery resistance and our voltage is fixed, the current too will be fixed.

This is the best I can explain!

Thanks Abhi, seems it makes some sense to me atleast for now

hi everyone i have a p200 and am not happy with the 35w setup need something much more brighter i have read some post and they suggest me towards avy 180 coil and stator plate so it gives a output of 55w correct me if wrong.but is my battery charging at the same rate at which its utilised or its draining because had used 55w bulb within 15 min battery is drained and horn becomes dim etc. had to push start the bike really pissed me off . so to run a 55w setup happily what should i do bec i mostly ride at night . ???????

guys really need ur comment on this one. pls help

Assuming that ur P200 is a UG4, DC lighting, has got a BCU. It has some limitations to enhance the charging rate as the BCU is very sensitive one, so tackle that is not that easy. U can try with the coil rewinding and RR swap but it may refused by the BCU. The best option for a better lighting is go for 35W bixen HID is a direct fit for ur bike, and no other alterations for this. If u use a Halo HID combi, dont forget to change the halo to a 35W very rare to source though else, u may end up with batt drain and left alone in pitch darkness.

Gurus, plz HELP!!

I own a Discover 135 (analog speedo). I want 2 switch 2 all D.C. m gonna use my stock 35/35 h/l & d bike is fully stock. wats ur final verdict, shud i go 4 it?

Here r a few ques, plz answer.
1. Components 4r d custom rectifier, is der any chng 4 my bike?

2. I suppose 'GND' (circuit diag) is 'ground' i.e. the earthed wire. Am i supposed 2 connect it 2 d custom rect bolt?

3. Custom rectifier circuit, r we gonna connect d -ve dc wire 2 earth?

4. The 'bleeder resistance', am i supposed 2 connect it in series aft d capacitor?

5. Which yellow wire m i supposed 2 connect my rectifier 2, d 1 wid a red line, i.e. Yellow wire wid a red line?

Cn i plz hv ur fone no, in case i need some help.
Thanx in advance!!

@Abhijeet Bhattacharjee, let me tell u one thing, pls type the words fully as much as possible atleast avoid the junk language usage, its good for the easy reading and better understanding of ur queries too. So pls follow that. We all like to conclude the things in short, but that should be convayed properly else, whats the point in postings Right?

coming to ur query, if u are going to use a stock 35W halo only the RR (XCD/Pulsar UG4 or any DC lighting RR will do) is required from the components end. Rest is re routing the wires.

Yes u are right, GND is earth and once u bolt the RR to the body no need of connect the earth it as the chassis is acting as earth. But the RR has got a earth wire to be bolted along with the RR.

Always stick to an OEM which offers a troublefree ride and stop worrying about the other queies, but if u are confident that u can make it then go ahead with that. Go through the full thread surely u will get an idea of what to do, Goodluck.

This is something I did a long time back.
1. Rectifier would be the same.
2. GND is ground.
3. -ve DC to earth yeah.
4. Where did you get that?!
5. I dont know abt Disco wiring. Mine has a yellow wire without any strips.

Basically only if you have interest in electronics, and have spare time, should you go for it.

**abhichotu.abhi** · 01-16-2010, 02:27 PM

Hi abhijeet,
Can you tell me basically what is the difference between
1) A ground
and
2)A negative terminal

I am too confused between the two.

I want to know how to ground a particular terminal on a PCB.

**abhijeet080808** · 01-17-2010, 02:48 PM

If there is only a single power source, both GND and -ve will be the same voltage level. But in case of an AC-DC combined system both may not be the same. GND is GND. (I mean zero potential!) But -ve may be at other voltage levels. In this specific case. the AC GND and DC GND are not the same. The AC potentials are say -6V and 6V at the 2 terminals (+ve and -ve) to get 12V AC. After rectification, DC will be 12V and 0V at +ve and GND terminals.

**Abhijeet Bhattacharjee** · 01-17-2010, 10:53 PM

@ Abhi Sr (I'm Abhi frm now).

4. 'Bleeder resistor' is connected in parallel across the capacitor to discharge it after the a.c. is switched off.
What shud b its rating? Will 5k b enough?

Ok, that means we take 1 a.c. input frm a wire & 1 frm GND & connect -ve d.c. to GND. (sry 4 d dumb ques, actually cnt see d pic properly cuz m on my fone.)

Btw, are you using this setup now?

+1 to that, proper usage conveys the idea better. And Sajjt, I have seen some SMS text in your advice too

no offence, just kidding, we are all spoiled fans of shortcuts but that should be very minimal. I got the idea.

Correction: 12V A.C. is obtained frm +/- 17V. Dnt 4get 12V is the RMS voltage not the peak voltage.

Yeah, its correct. And that resistor should be something more, like 100k or so. I used this set up for a month or so. Now, I am using a rewinded coil + custom RR unit. Wanted more light you see! Now its a 100/90W h/l.

I know. Was just giving a simple example.

Thanks!

I have only shared what I know!

AC to DC converter for my bike

Dear Abhijjet,

Can you make one recitifier for me which is use to convert my AC to DC power from my Pulsar 150 Dtsi, Digital Meter, The model is Jan 2006. I want to install HID kit to my bike. Pls help to get it done. my email is sanjay548 at the rate of hotmail dot com. i m from ahmedabad. if possible give me a miss call at nine six zero one two six nine eight five seven. I will call you back.

Thnks & Rgds,
Sanjay
