@asjdsm - Bro thats why i excused, for posting it here. @imranbhatti - let me tell you the situation. The rectifier which i have is from the same 3 wheelers ( which you mentioned) but problem with it is that it is not controlled. Means it over charges. Over charging creates question marks for battery's life. The battery which my bike has is swelled up because of over charging ( the reason why this rectifier was installed in my bike was that it has HID and the electrician who installed it mentioned that because of HID you gonna need some over charging).
Now my current electrician, is saying that your battery will be busted if you keep on using it. He recommended to use any rectifier from heavy bike which 5 or 6 cable ( according to him 5 cable rectifier is automatic one). Since i dont know much about this part, so i have to rely on the electricians knowledge.
Now please suggest from where can i get it?
