    Hella 400 HZ 12 V horn

    I have problems with my signal horn on my 1967 911, relay is clicking, horn pad, contact is fine , relay is fine, power on wires to the horn.

    I took the Hella horns of the car one 500HZ on the right side one 400HZ on the left. It is Hella 002 924 , are these correct for my car.?

    I wired 2 wires one 12 V + one wire from - (minus) on a spare batteri to the horns, no sound from any of them..... Have I done this correct?
    or do I need a seperat ground?


    where can I get coorect new Hella horns?

    thanks

    Hella still makes trumpet horns in 400 Hz - 500 Hz pairs although they look somewhat different: http://www.myhellalights.com/index.p...-trumpet-horn/

    However, the parts catalog describes the horns for 1967 Porsches as:
    901.635.112.02 fanfare - BOSCH 400 HZ - /L
    901.635.113.02 fanfare - BOSCH 500 HZ - /R
