G'day Gaz,
Try looking at the blue relays in the heelboard fuse boxes. They are both IGN power relays and if they don't "click" when you turn the key to ON then you'll have a dead car electrically.
Take the heelboard covers off and while sitting in the drivers seat turn the IGN on and off, you should hear the relays click. If they don't then pull them out and re-seat them. Sometimes it is just a poor contact in the relay socket.
Both of mine failed at the same time while driving would you believe it. The car just drifted to a stop quite dead.
The horn relay is identical, lives in the LHS underbonnet fusebox and that circuit is always hot so you can test suspect relays in the horn relay socket.
Cheers and good luck,
Jeff.
