    Computer malfunction



    My daughter has a 1987 Coupe Deville which was sitting idle for several months. There was a drain on the battery and electical went dead.
    Problem upon restarting car is that digital readings on dash are all jiberish now and unreadable. Is there a sequence for rebooting the computer system so that dashboard information is readable again? This is my best guess as to resolving problem. Any advice appreciated...
    JK.... freezing in Alaska

    Disconnect and then reconnect the battery again?

    Ummm... I had an 85 and the computer would always reset when I disconnected the negative battery cable. I would say to make sure you leave it disconnected for 20 minutes or so. If you've already done that, your computer might simply be in need of replacement ... I am surprised if that's the case and absolutely nothing else appears wrong with the car. It should be noted that there are other chips and computer-controlled parts that could possibly be a factor (EPROM--stuff like that) that I don't know as much about . Good luck regardless.

    Oh yeah and P.S... Do you know what the electrical drain that you mentioned was? Sometimes, if an aftermarket stereo or something is put in, and not hooked up to the right power source (I had this happen...the ignition can cause problems on these fussy cars), it can cause a power drain which might have screwed things up...
