Trip Odometer and clock resets when iignition switch is turned off..

Has any one had this issue that when I the ignition switch is turned off, the trip odometer and clock resets back to zero and 12:00(respectively). Also, my radio needs to be turned off manually even when I pull out the key. I am thinking the ignition switch...!!! Thank so much for any help..

Oh, almost forgot, the fuel guage and temp guage needles remain where they were when I turned off the Ign switch..

That's pretty much a standard dead battery symptom.
You're able to start it O.K.?
If it's not the battery, check all the large wires and connections up there, both ends.
There are some main grounding lugs under the battery tray.

Thanks, yes, the battery is fine...I will check the wires as this started when I changed my alternator(pully exploded) back in april...
