Check the voltage at the battery. If you don't have a meter you can get one for around $15.00. You should have at least 13.6 volts DC but not more than 14.5 Volts DC. If you have proper DC voltage then test with your meter on the AC scale. You should not have any volts in AC. If you do it indicates a bad diode in the alternator. Many auto parts stores offer free charging system checks.

The ford escape is a very temperamental car to say the least. The light could be coming on for several reasons. The escape has many sensors that can short circuit and cause the light to go on. I recommend taking your car to autozone. They will test your car out for free and narrow the problem down. Then you can go from there. Fix it yourself or take it to a mechanic.
