My car is not just clicks when I turn key.just replaced battery . on 1998 Lincoln Navigator

Check engine light recently started coming on

Asked by for the 1998 Lincoln Navigator
check charging system alternator, and starter, most automotive chain stores do it for free, visually check for corrosion build up,check wires /cables to starter and all areas, if check engine light is on the vehicle may have set a code get scan to determine problem, do not continue to purchase parts with out the part fixing the problem. Is battery new or used? check battery voltage 12.6 volts is fully charged battery. look for lights or other things that may be on when the vehicle if off (drains on battery) cut off everything before you exit the vehicle.
Thank you ! We will try this
