hi everyone , i have a 79 350 and the other day i was listening to the radio in the driveway . went to start after a while and was dead no big deal right?? went to jump it and as soon as the cables were hooked up she tried to fire up no key in ignition !!! figured something was screwy with the switch so i put the key in and turned it back and forth a few times , then tried jumping it again . it worked... so couple of days later get in my truck and she starts right up.... but now the radio won't work ?? there is power going it because the security light behind the face is blinking and the cig lighter works -same power source. so could whatever is in the switch that makes the radio come on be bad or what ???? thanks in advance for any help .. thanks
