Check the 175 amp mega fuse on the front of the engine compartment fuse panel. Replace this if it is blown. Check for shorts to determine why the fuse is bad to begin with.
No, as being a master mechanic, it would have nothing to do with it.
Good chances are, the alternator is not connected correctly or is defective.
If you have already checked the connections on the battery I would suggest testing the alternator and the battery. If the battery will not take a charge or the alternator will not give a charge you could have similar problems.
It can, though it is unlikely -- the alternator and the voltage regulator would both have to be faulty. A faulty alternator will not charge a battery, though, so it may seem normal until the charge put into the battery at the store runs out.
only if it doesnt have fluid.
I would check your alternator*(check the spelling).
If the alternator is good and the battery does not charge, then the battery may be bad. There could be problem with the electronics. You will need to take it to a place where they sell batteries. They have equipment to check out the battery and the wiring.
It would only run as long as the battery had a sufficient charge.
I have a 2.0 1995 Mercury mystique the battery charge light was on no output on old alternator. Replaced alternator No output from new alternator "charge light out" (wiggle test wires& re-check wires) at alternator *still no output* is there a fuse that could be the problem or just another bad alternator... I would check the alternator plug before getting another alternator, it may be bad. And is a lot cheaper to replace.
Brake Booster needs replaceing
On a 1991 Lincoln Continental : I'm not a mechanic / technician but I have never heard of aluminum heads for the 3.8 litre Ford V6 engine So , I would assume they are cast iron
The positive cable between the alternator and the battery has an open circuit or break. There also is a set of wires that plug into the alternator that turns it on when the car is running. Wiring problems here can cause a alternator not to charge on the vehicle but works fine on a test stand. Some cars the alternator light in the dash causes the alternator to kick in when the engine is started. A burned out light in the dash causes the alternator not to charge.
