replaced battery and lights, horn, fan and wipers come on but no dash or igniton

What is your question?

I connected the positive terminal and the vent tube as directed, and when I connected the negative terminal, the horn, lights, wipers anf fan came on and wouldn't stop. No dash functions or lights, nothing from ignition switch. I disconnected the negative terminal, leaving positive cnnected and waited 30 min, but when reconnected negative terminal, same result.

How long has your 2002 Volvo S80 had this problem?

just snce new battery connected
