Connect a good ground to the horn terminal with the purple-black wire on it.
If that doesn't startle the local wildlife check the voltage on the purple
terminal while you have the ground on the purple black. If the 12v on the
purple drops significantly you have a high-resistance back to the fusebox
and the brown circuit. If the 12v doesn't drop then you have a duff horn,
or two. You may have to check both horns this way, in the UK the wires go
to the RHS (as you sit in the car) horn first then to the LHS horn.
