I have a 1983 280ZX that has a radio that's misbehaving. It will not remember presets after being turned off for an hour or so. I have also noticed that sometimes the antenna goes up when you turn the radio on and sometimes it does not. I have been gone for two weeks and went out to the garage and turned the radio on last night without starting the car and the antenna came right up as soon as turned the radio on. Although my battery voltage was in good shape (12.3v) I decided to top the battery off with a trickle charge overnight. This morning I go back out with a fully charged battery (12.6v) and tried it again and the radio came on to the AM band (no presets) but the antenna would not come up. The car had sat idle since the night before so I have no idea why that worked last evening and 12 hours later it didn't. Another thing I've noticed is that the radio does not come on automatically when I turn on the ignition like it once did. I now have to always push the button to turn it on after turning on the ignition. I can find no rhyme or reason for this. I have thought that it might be dirty connectors but then again I wonder if its just the radio. If anyone has any insight on this I would appreciate it.

I have a 1983 ZX that had a clock with a display that would go dim and almost out, My first response was to replaced the clock. I found another clock and had a mechanic install it. At first it worked fine but after time it started going dim like the original one. On a hunch I took the original clock that was removed earlier and hooked it up to a power supply and it worked perfect, the display was bright as day and it worked fine. Now I am back to looking at a wiring problem in the console rather than the clock. I wondered if there was a way inadequate voltage was reaching the clock. In addition to this issue I have also noticed that my cars radio will no longer remember stations when it comes on, it comes up on 550kz on the AM band rather than the FM station I left it on. I then have to hit seek to find a station. If I turn the radio on and set it to an FM station and let it play for a few minutes and then turn it off and back on, it will come back to the station, but if I turn it off for an hour and try it, the memory is lost. In addition to this I also noticed on a couple of occasions that right after I started the car the radio came on for a few seconds and then went off all on it's own. When this happened I could usually hit the power button on the radio again and the radio would come on and stay on. I might add that there does not seem to be any low voltage problem in other areas of the car. Everything else electrical works fine and the car starts right up every time. I'm not an expert on these things but I'm starting to think my radio and clock issues may be related in some connector in the dash. Anybody expert opinions appreciated.
