    In that case the circuit is good. Practical testing matters much more than theoretical concepts. Btw, where does the relay fit in the circuit? And which diodes and capacitors have you used? Any circuit of the rectifier?

      The rectifier diodes have to be bigger IN4007 won't work, even after that the diodes will heat up a lot, a smart design with a heat sink, will do the trick. It may sound complex but it's easy one time effort!
      I am not a electronics guy but given complete circuit diagram i can solder them and make it work (i hope so)

      So can pls gimme a pictorial representation of how u r bridge rectifier is designed?? Or can i get a rectifier of some bike and just plug it??

        The relay is used only in case of Pulsar UG3, 200 family. As Pulsar UG3 don't allow the bike to be self-started in case bike is on DC. Thus the relay uses the AC power from the coil, to judge whether the bike is on. And then puts the bike on DC. Works quiet efficiently.

        I will try to up few circuit diagrams, which were put on the forum ages back. But yes, you can just plug any rectifier. The problem is of space and cost.

          Series 5 diode used in this case.






          The relay part is only for PULSAR UG3

            Thanks for the circuit. I am interested in the first circuit. I have a P150 Classic. I did not get the 5 series diode part. Can you specify the specific diode number - 5xxx?

              I don't remember the number, but it's called the H6. Basically similar to IN4007/1 but larger in size and higher tolerance. Capacitor would be anything on the higher range. eg: 35V, 3500uf or more.

                Oops now how will i know which is the diode.!!! Can someone else help to get the diode number?

                  5 series diode - 1N5400. Is this the one rahuldevnath?

                    Actually, I got it. It's 6A4

                    6A4 (Diodes) - 6.0A SILICON RECTIFIER

                      Thanks for confirming. I thought it was the 5400 - it can handle upto 3A (36W). 6A4 can handle upto 6A (72W). Since we are using the diode at about half its rated capacity (for a 60W bulb), I think heat would not be a problem. But you said you still needed to use a heatsink. If so, can you please tell how you attached the heatsink to the diode? Soldered one leg of the diode directly to the heatsink? But I guess that would be risky and may cause short circuit.

                        So that diode number itself is 6A4 ??
                        Sorry i am completely zero in such things so need pin to pin info
                        And ya even i need to know how to put them inside heat sink

                          Well yeah, the diode number itself is 6A4.

                          Coming to heat-sink, it's not mandatory, but my old rectifier went kaput after 2 months of installation. These diodes will heat easily up to 100+ degrees.

                          For housing, and heatsink use your creativity suited your bikes depending on the space u have. I will put a diagram of mine.

                            That will be much helpful to become more creative

                              Keep in mind 2 things.

                              (1) The components should be securely place inside, the housing, with least amount to moisture left to enter.

                              (2) The heat sink should be outside, still away from water. The wires connecting diode over the heatsinks, should be solid and very good condutor of heat.

                              BTW I have made use of the plastic shell of 6V relay!

                                That is a very clear diagram. These two heatsinks will result in a short circuit if they come in contact with each other or with the frame of the bike. So, installation should be secure!
