Hi all

Last year I replaced my horn by a new horn ( not a VW horn by the way). It
was working fine last year ( I used it maybe 3 or 4 times).

This year my horn is not working anymore. (works fine if I put 12 Vdc
directly from a battery). The ohmmeter is reading about 1.2 ohm from the
horn terminals. The voltage drops to 7 Vdc at the horn terminals when the
horn switch is depressed. If I connect the brown/blue wire (horn end) to the
frame and measure the ohm between  the brown/blue wire (steering end and
disconnected from the slip ring under the steering) and the column steering,
I got 0.5 to 0.6 ohm.

My question is : Is it possible the impedance is too low on this horn? What
is the impedance for a VW horn? It looks like there is a lot of voltage drop
trough the wire going from the horn to the horn switch. Is there any other
wire junction between the horn and the connector underneat the steering.

Thank you
