If I flick the indicator stalk to get full beam the horn sounds. WTF

..... Any ideas why this should happen???

Sounds like you have a touching wire someware.
The wires possibly living the steering column and setting the horn off?

Or possibly a problem behind the clocks. Wiring again :mrgreen:

Did you find out exactly what caused this?

Mine did this in the past, although it was only triggered occasionally by indicating right.

Have now fitted a new indicator unit.

Disconnected the horn and refitted via a separate switch. I guess it is a wire problem from the horn via the steering tube... probably a short somewhere

The horn ring must be connecting in someway to the indicator switch and when you operate the main beam it's providing an earth to the horn. I would start by having a look at the indicator switch for any contact around the steering wheel/column.
