Run direct power (+ and -) to the horns themselves. They should sound
loudly.

The purpose of the relay is to allow the switch wire which runs up
through the steering column to be a ground switched wire, as opposed to a
hot-all-the-time-non-fused-let's-start-a-fire wire. When you push the
horn button, the contacts connect the purple/black wire to ground. This
grounds out the coil winding in the horn relay, and the relay closes.
This "switching" inside the relay sends positive power up to the horns
themselves, which begin to beep.

You may not be able to access the grease fittings with the car
assembled. This is how some people get the odd notion that British
engineering leaves something to be desired. People are funny that way.
