You run the risk of damaging the alternator.
Easiest way is to check the voltage your getting out of it when you have electrical loads on (headlights, radio, blower) If the alternator is faulty the voltage would be low
which one the power steering,alternator,crank or a/c,crank?
how do i change the alternator in my 2001 ford focus?
The voltage regulator is attached to the back of the alternator with 4 torx screws for the 1991-1995 models non-integral type.
Ford didn't make the Escap in 1991.
I would have the alternator tested. If the alternator is over charging the battery then it is just cooking it.
