Horns are a REALLY unreliable item -- not just on Jaguars, but on just about any car. The problems always seem to be in a set of points within the horn. As the diaphram vibrates, it makes and breaks the points, providing the on/off current to the coil moving the diaphram. Apparently either these points get corroded from not being used often enough, or burned from overuse, or whatever, they are always troublemakers. Here's a project for the electronic weenies here. How hard would it be to fabricate an electronic oscillator to provide the suitable on/off current to the horn? Simply hotwire the points within the horn (easy on Jag horns, they come apart with screws), and connect up the oscillator into the supply to it. When installing, a variable pot could be adjusted to match the frequency to the resonance of the horn (max volume). Kinda like the old electric fuel pump fix. -- Kirbert | If anything is to be accomplished, | some rules must be broken. | - Palm's Postulate |
