1997 jeep grand cherokee computer

I set the time and date in the computer and it will
stay updated as long as the jeep is running. When it is turned off and restarted the time and date function
is flashing and has to be reset.I have checked the fuses and the mileage to next oil change retains it memory. Any ideas? Thanks

sounds like your battery is about to die on you, check the Voltage first. turn engine off and wait a couple minutes so that the voltage stabalizes it self, 12.5V normal, 12.0V low, 11.0V dead.
Check you Alternator, leave + - leads connected properly and with the engine ON your voltage will be as follows, 15.0V high, 14.0V normal, 13.5V low. a low charge will not fully charge your Battery. also test your Ground connection, this can and will affect your entire electrical sytem, hope this helps.
