The check engine light could be from changing the battery. Some models will do this saying that there was some loss of power recently. My Jeep does this. I would get a hold of a code scanner and check it, because you just wont know what it is until it is read. Autozone will read your computer for free, but I don't think they will reset it. The trouble code has to be erased with a trouble code reader. Also Make sure your emergency brake is also all the way off.
AnswerThe key here is that each warning light is trying to tell you 2 different things. They are not likely to be related to each other.
Research each light separately.
NOTE: Fix the *cause* of the trouble codes and the lights will turn themselves off.

Replacing battery terminals??? How did you accomplish that. Do you mean you replaced the battery or are you referring to the battery cables? If you replaced the cables are you sure you have them connected correcty and tight. Especially the ground connection. Take a reading with an ohm meter from the neg battery post to the engine or chassis. If the circuit is open, you have a bad connection.
Facing the engine from the front of the vehicle, the battery is located in the right, front corner.
Could be the head gasket. Very common problem with this engine and model year Windstar.
Replacing the battery was not likely the cause of your check engine light. Most auto parts stores have a code reader will read the code for you at no charge and reset the light.
My check engine light came on because the terminals were not connected tightly. no. quite the contrary. if you have a "check engine" light on, disconnecting, or in this case replacing the battery will turn it off. you have a different problem.

Wow, um, just wow. Anyway, did the engine crank over before replacing the computer? If so, during the process of replacing the computer did you create a problem with anti-theft or did you forget to reconnect the battery?
It depends on the engine and situation. Sometimes the water pump, idler puller, or tensioners need replaced also.

When replacing battery, when servicing some part of the engine, or when the vehicle is not going to be started for over one month.(keeps the radio memory from draining battery)
In general, since you replaced the engine, you most likely disconnected the battery - and that should have reset the codes. If you are getting new codes, something is wrong. Perhaps you have a wiring error or a disconnected sensor. Perhaps one of the sensors is bad.
