I just installed a Eclipse 12 disk Cd changer in my 97 F150 Xcab, and luckily the changer works but now the the radio acts like it is not getting any power. I checked the wiring for voltage to the plug on the back of the radio and it is has power. I checked all the fuses under the dash and they appear to be fine. Is there anything else I could check before taking the radio in to have it tested?
