hi,unbelievable as it is yesterday i put jump leads onto my rx300 the wrong way round,they were on for a couple of minutes until i noticed the leads were melting,i bought more leads today and put them on the right way round but,the lights come on on the dashboard but the steering column didn't move and there was no life in the radio and not even a click when i tried to start it,have i fryed the battery or could it be a fuse,
