i have an 01 land rover discover 2 i changed my battery myself (bad idea) put the negative on positive by accident caused a little smoke, my neighbor came and tugged at my wires (bad idea too) to make it reach the right side..after this my radio does not work..everything works but radio and it drives fine..clock works too..fuses are fine..can you tell me why my radio does not work?
you have totally destroyed it. Also you will ave damaged the alternator and regulator. Also the engine management system is unlikely ever to regulate properly again.
