Electric Problems

Hi to every one. I hope some of you can help me.

I have a Jaguar JX 40 XJR. Today I changed the old and non-functioning battery. I connected the poles and heard a bip alarm. No spark while connecting the two poles. Turning the ignition key I noticed that the dashboard lights did work. Nothing going in the dashboard. The odometer has strange numbers (it seems crazy). The engine start but no indicator works. In your opinion what could be happened.

Thanks

You have to post your year and vin number as the cars differ quite a bit across the range.
