    69 radio

    I finally have my car pretty much back together however I went to start the car yesterday and the battery was dead. So I charged it up then I noticed that after starting the motor and running it for a while, I turned on the radio and it was working properly. Then I turned off the radio and the motor and I could faintly here what sounded like a radio and sure enough I was hearing the radio with it turned off. Has anyone experienced something like this?

      Does your car have a "pet name"?? Christine is one that comes to mind...

        I have not experiaced this on my 69, but it sounds like the switch on the radio is not turning off the power. Just my two cents.

        I have the Oppisite problem, I turn my Radio on and all I get is a pop in the speakers.

          That only happens on Red Plymouths with extremely bright headlights...

          Jim, I'm no electric expert, but is it possible that your On Off / Volume switch has some play in it that may be sending current to still be on?

            On a more serious note...
            If the key is in the off position, shouldn't there be no power to the radio? Not to mention that the radio would also have to have an "on-off" issue if is was turned all the way off? I have seen some pretty strange things (some never to be fully explained) when it come to having shorts or something back feeding through the system over the years. Seems as most of those types of probelms I have run into over the years were "ground related", although that may not have anything to do with your situation. Eliminate things one at a time and sooner or later something usually shows up?

                Terry is exactly right. Your dead battery is also an indication that your ignition switch may not be off and power is running to your ignition system, alternator diodes, etc. draining the battery and possibly over heating your ignition coil.

                  Thanks for all your suggestions. I didn't realize that the ignition lock was not the ignition switch, so I'll need to look into why the radio is getting power with the key pulled out to start with. In addition to that, I agree with a couple of the posters that the radio on/off switch must be dirty or faulty to not turn the radio completely off. Looks like the radio is coming back out, oh fun. Pretty spooky jim

                    If the radio continues to work with the radio switch turned off you have another problem than the ignition switch. I suppose it is possible there are two problems, but more likely the problem is in the radio itself. If you can reach the electrical connections for the power and light (I think they are on the driver's side near the forward (toward the front of the car) part of the radio try to check and see if the electrical wires are connected to the proper position. The gray wire will be for the radio light, but I don't know which of the others is power and which is ground. Hopefully someone else will.

                    BTW: Many people are not aware the ignition switch is located above the brake and clutch pedals and not where the key is inserted. It is mostly auto technicians and car thieves who know this.

                      If I remember correctly the gray is the light, the hot wire is yellow and the ground is black. I will check the wiring diagram and correct myself if it says otherwise.

                        Jim, the switch has a bit of lubricant on the moving parts inside it and it does what all grease does over time - turn to glue. The 70 that hit the bench tonight had that haunting "stuck on" problem. Usually they're stuck 'off' as the radio has sat in that state for many years.

                        And don't be temped to blast the switch insides through the slit openings of the volume control section with that infamous fix all - tuner cleaner. Both the volume and tone controls have carbon deposited tracks that an arm rides on and chemicals will loosen the particles unless they are cleaned out.

                        The best way is to disassemble the control and clean the switch section separately. Naturally, the switch is the last section in the dis-assembly process - Kilroy always wins. It can be fixed though.
