i recently tried to install an after market radio in my c32 laurel, however the wires got mixed up and there is no power to the whole centre of the dash(ie ac, deck).......wen i checked the fuse box...the whole accesory panel is not gettin power and 1 of the relays above is reading 3.6V while all the others reading 12V..........wat can be the cause and how can it be fixed?
