The horns on Ms Triss have been less than optimal for a couple of years, so, I finally decided to do something.
I bought a pair of new -much louder - horns and tonight went to install them.
You will recall that a purple wire comes directly from the fuse box to the horn - it comes to the drivers side (LHD) plugs into a spade on the horn and and then continues to the passenger side.
Similarly a purple wire with a black tracer comes into the driver's side and then continues to the passenger side. This wire also continues to the steering wheel where the horn button is the switch and everything is grounded at the steering wheel.
So, I hook up one horn - driver's side - loud as can be.
I hook up one horn passenger side - loud as can be.
I hook up both - nada. well not quite nada - sort of a wants to work noise but not even a fart.
I swap them - individually - lots of noise (both horns work for sure)
I even swap wires - purple from drivers and purple/black from passenger - lots of noise
two horns no noise
I swap the wires on the horn no difference (they don't have polarity do they?)
I check the purple wires - each showing a solid 12.4V
I have continuity in the purple/black wire from the plugs to the horn button
I am pulling my hair out.
any thoughts?
