Hello I have a 2000 Jaguar S type. Jumper cables got put on backwards and since the vehicle will not start. Put new batt. checked all fuses and relays everything looks good. The odd thing is that customer said all his windows work only one working now is the driver front also radio turns on but i didnt check for sound but it did turn on however, there are no lights working in or out. Vehicle has an aftermarket radio and customer said that once before a similar problem had happened vehicle needed to be taken to jag for some re wiring in the dash behind radio. Any ideas? Thanks
