i have a problem every time i push the horn the radio and clock go off it do not reset just interuped the power and theres a clicking under the bonnet near the bulk head
anyone got any ideas

thanks

Sounds like you've got an issue with your horn relay, it's possibly shorting something else out whenever you give it power.
That's where I'd be looking.

any ideas where i would find the horn relay thanks

In the main fuse box under the bonnet, generally pretty close to the battery.

thanks for that
i had already changed the relay but its still the same,
the clicking is coming from under the intake manifold any more ideas i cant find anything

It still seems to me like something is shorting out. Maybe your loom is a bit frayed and shorting out on the block somewhere? Try and track down the clicking.

ive looked over the car again and i think its the starter solinord thats clicking the spark is going to take a look...
i will let you all know
