Normally when you replace the battery you disconnnect the computer and it should clear any codes stored. (The codes are what turn the check engine light on.) More than likely the cause of the light coming on is due to a vacuum line that was pulled loose when installing the battery. I had the same thing happen and it was caused by a vacuum line going to the cruise control. As soon as the line was reconnnected the light went off. You may want to have the codes checked by a reliable source such as Car Quest or any good mechanic if you can not find the problem. Autozone does the code check for free!
Yes, it's possible, but unlikely
Check for a weak or dead battery Check for loose or corroded battery cables Could be a seized engine Could be a bad starter or bad starter solenoid

More than likely the battery has a dead cell and needs replacing. It can also be something is on pulling power from the battery.

If your 1997 Mercury Tracer has a battery light that blinks on and off while the car is running, it most likely means that the battery is not charging. This could be an issue with your alternator.
It should restart normally after replacing the battery. If not, it could be a security mode the car has entered. You should question a ford dealership about it.
