I noticed that after I installed an after market radio by Custom Autosound my dash lights no longer worked and found the fuse was blown. After replacing the fuse it blew immediately again and again. I used all the original radio connections, power, ground and speakers when installing the new radio and the radio works fine. I disconnected the power and ground from the radio, put in a new fuse and the dash lights work fine again. Has anyone else had a similar problem. If the radio continued to work fine how could it be linked to blowing the dash light fuse?
