Vstn, I merged your two threads on this problem. Duplicated threads lead to confusing responses that can waste your time. I wanted to delete the second post here, but I can't do it until the redirect expires.
To clarify, you are saying the horn will make noise if you apply 12V to it, but that it is only getting 4V, right? And, you want to know how to supply the needed 12V.
