I got a problem when I tried to change the headlight for my old 89's 240sx. I just followed the user manual, disconnect battery negative terminal, change the new headlight, and reconnect battery.
After that, however, I found I couldn't start the car any more. Whenever I open the door, the four side markers ( the small lights on each corner) kept flashing, as well as the clock on the dash board. And I heard some click-click sound. This will last around 1 min until it goes off. All these happened even before I plug my car key.
Since all the lights are still on, and stereo also works, it won't be bad battery. I doubt if it's due to the electrical system. Now my car is dead there at home. Hope I don't have to tow it to garage.
If anybody can give me some advice, I would really apppreciate!!!
Regards,
Ben
