No original coil is not self regulating there is a regulator for 35W bulb. But When i try to use 60W through that regulator, it was glowing like a candle, therefore i tried directly. and stated in second last line.I would suggest you can't do it without rewinding the coil, but then you have the problem that the original coil was self-regulating, so may need a regulator to not blow the bulb.
My stock battery is 2.5A and the max i can get from my stator is 5 Ampere. Is this optimum to feed a battery?I've always thought the solution would be to add a decent size battery, feed the headlight from that, and rewind to provide a decent charging current, complete with regulator.

I've to take several test because it will exhaust in low rpm.
Yes i agree, that is why i got confuse, whether to go for re-winding or not, I dont know i'll see any improvement coz one guy has re-winded (shown in the forums) and got fail. Haven't seen any improvement, after consulting with a mechanic, he said u need a bigger magnet.A 60W bulb takes 5A, so you need more than a 5A alternator, which is why it needs rewinding.
Yes i know manA 2.5ah battery is obviously far too small - in my experience they struggled to keep the indicators flashing when you stop at a junction! (and you couldn't keep the brake light on for long).
I've a 100cc CD Dawn bike from Hero Honda having 12v@2.5A battery used only for blinkers and horns.What bike is it? What is the battery voltage?
white headlights are baned in most of the cities in my country also u will feel difficulty in driving while there is a smoke or fog, normal bulbs are better specially in yours (colder) countries in off seasons, it reduces the chances of accident.If your headlight is 35 W, 12 V you can't do much about increasing the power. I would nowadays go for LED lights, but you would need good smoothing and regulation circuits. White LEDs didn't exist in the early 1980s.
I dont know whether LEDs headlights is available for my bike or not...most probably not.The generator will only produce around 3 A, whatever load you connect to it. If you want to increase the current, you would have to reduce the number of turns.
You could see if you could find a replacement bulb that is made with yellow LEDs.
Thanks for the brief explanation.....but what about the power? What theory says, if u increase volts ampere has to be drop and vice versa but output always remain the same....So with twice as many turns, you get half the current. Similarly with fewer turns, you get more current. Of course, the engine will have to be going faster before you get full brightness.
The output power, which is voltage multiplied by current, will not remain the same if you change the number of turns.Thanks for the brief explanation.....but what about the power? What theory says, if u increase volts ampere has to be drop and vice versa but output always remain the same....
The voltage multipliers won't help you increase the power. The wire gauge won't make much difference, but it you use wire that is too thin it will reduce the current and it might overheat.If i get more current with fewer turns the voltage will drop, hence poor brightness on low rpm. On the other hand if i increase the turns ampere will drop and again there is a problem. Am i right? If i want to increase volts i wud go for voltage doubler method
**broken link removed**
but that doesnt make any sense.
What about trying thinner gauge of wire?
Yes I've measured 35v with no load, direct from the alternator.think that you measured 35 V from the alternator with no load at high engine speed, so you have plenty of voltage if the engine is running fast. However, you have too much impedance in the winding. You need to reduce the impedance by reducing the number of turns.
That is not blowing because of a regulator....I suggest that you measure the current that the alternator produces at the various speeds.
I don't think that you will get 5 A. The headlight only takes 3 A, and if the alternator can produce 5 A and 20 V it would blow your bulb.
Sorry i could not understand about which transformer you are talking about??Have you considered wiring in a common 24 volt center tapped transformer to your alternator output and use the center tap as a 2:1 voltage divider?
A 30 VAC transformer? what will be the output?Given that it would be working in an auto transformer configuration the transformer would be only handling half the power so a common 30 - 50 VA size would be more than enough to power a 60 watt bulb.
Yes a common 12 - 0 - 12 secondary or anything close to that.
VA is Volt Amperes which is how transformers are rated.
