Hey Guys!

Just read through this whole thread. Must say I'm very impressed with Rahul's and pavan's ideas. Great job buddies .

Now, I've recently been moved into the night shift at my place of work. That means either taking a company cab, or taking the bike. I have a 2.5 year old P150 UG3 which is in quite decent condition . It has been slightly modified with the stator plates from the Avenger and a 55/60W headlamp. Illumination is pretty decent but yeh dil maange more . I am considering taking the bike to work at night. So I want to spruce up the lighting

So, I was thinking of getting the DC setup done and then perhaps plonking in the OSRAM Nightbreaker or an HID setup if budget permits :P. Trouble is I'm totally useless with circuits and electrical components.

I tried to understand what has been done, but the technical terms kinda flew all over my head. I didn't understand what the relay switch was and how it can be made.

Can someone please elucidate on it?

I need a simplified wiring diagram if possible :P

I'm sorry for being such a moron

Hope you guys can help me with this.

Thanks in advance.

Sourav.

Hi Sourav, as you are already running a 65w bulb the only way to actuallly improve it is go for an HID setup. Now to convert the bike electricals to D.C it would be really difficult for you to work on if you don' t have atleast the basic electronics.Like working with diodes and stII would recommend you ask your friends who can help you locally, or who can work on circuit provided here. Because even if you sucessfully make the circuit it may or may not work properly and then it needs to be diagnosed. You wilso need soldering kit, and other components as well.

May or may not work............aimed at me.......hehe

look relays can be used as switch and many other purposes,the main thing that a relay has in its internal circuitary is a small transformer(desi language mein) which works same function as our EB
(electrical) transformer does it provides more current ,say relay of 40A

Dude you have got it wrong. A relay doesnt have a transformer inside. It has a coil just for magnetisation of armature.
It by no means provide transformation or provide more current by any means. A relay can provide only that much current provided by the source. it cannot boost current. It can Withstand lareger currents flowing thorough it which our normal switches cannot.

So basically our stock switch switches on another switch-the relay and the relay completes the load circuit, this way there is minimum current flowing through the stock switch as the heavy current going to the load is travelling through the relay. The stock switch just activates the relay and the current required to activate the relay is very small.Thus we use relay to save stock switches from conking off.

as far as i am concerned about transformer i have said it for easy understanding but i am sure that relays boost voltage without any additional inductive reactance. i have got it right pavan

and relay is not only used as a switch if it would have to be used only as a switch then there are 1000's of alternatives for it

Hmm, right you are mate. Well, thanks for replying to my queries and my PM so quickly.

I shall wait till the 26th when you are back in Bangalore. Will see how things go from there No sense is bugging you when you are not in town .

Thanks for the help mate. Will get back to bugging you on the 26th

Not really, even I didn't suceed the first time, though I had always use Fuse then.

The relay + transformer part went above my head. Rahul comment...plz

a relay has windings inside it which work similar to a transformer you took exactly as a Xmer

Relay - Wikipedia, the free encyclopedia


It doesnot specify anywhere a relay providing a voltage boost or even a current boost. You must have mistaken it with a transistor.
The relay doesnot provide any kind of amplification. It is just a switch.

you are not understanding the point that the relays used in bikes,cars,....
are the induction relays. they are meant to regulate flow of current.

what this wiki says is right that relays are used for switching purposes
i have never said that they are not used for switching. but, please understand this that relay supplies constant current by regulating flow of current that is the only reason that a relay is recommened whenever we
for e.g You want to fit two horns in stock bike,... then to match the ratings of those horns you would need additional power inorder to make the horns work perfectly without affecting performance of other equipments like headlight. relay will regulate current supply as needed by the horns or any load. hope that this will clear your doubts, i am not saying nor i ever said you are wrong (relays are used as switches) but i have only made a small correction in it. or i am trying to clear your doubt which i think you have...

if now too you have doubt then please search for "induction relays" on net
and you will find your answer. i have reached my capacity.

Dude when we install two horns we install a relay so that the current drawn by both the horns together doesn't burn the stock switch due to overcurrent. The stock switch was designed to handle current taken by just one horn. But when you want to install 2 horns, the current drawn by both of them may exceed the max current ratings of the stock switch. To save the switch, we use a relay. The relay doesn't regulate or anything. Its just a switch. The current required for the double horn for eg will be supplied by the battery. There is no way that the horns would sound just right even if their current requirement exceeds the battery capacity by just installing a relay.

A relay on being energized, just completes the load circuit. As soon as it is de energized, the circuit breaks.
This is the sole purpose of a relay.
