Can't see how that would be possible. An alternator can boil out a battery if the car is run with a dead battery, but a battery "shorting" out an alternator?

Sorry, but no. Whoever told you that is either clueless or is lying to you.

No. It's rubbish. Take the car elsewhere. Ideally a Ford garage.

It happens all the time. The battery goes bad, the alternator, which is designed to charge the small loss from the battery on cranking and run your ac, radio, fuel pump etc now continues to charge at high rate, the internal heat goes beyond normal, solder connections melt, plastic insulators too… First saw this in 1987 on a high output GM alternator… Usually someone jump starts their car and thinks they'll "charge" the battery by driving the car, then they need an alternator too… You can see the heat damage in some alternators without taking them apart… Technically the alternator killed itself, because of the bad Battery… Short answer, Yes

A battery is loaded with both positive cells and negative ones. They are placed side by side or back to back. Old batteries start to break down inside. The material used to hold the voltage begins to float down like dandruff on your shoulders. At some point the material creates a bridge and when this happens the cell shorts out, but only this cell! Each time this happens the battery looses the most needed part of a good battery it's amp power. A 500 amp battery now puts out 450 or less. Trust me this is only for a short time though because another cell is coming soon to fail. It takes amps to spin the starter as well as volt's. It is slightly possible to have a very bad battery fully short out and this could cause an issue to the alternator but not all that common. Most often its a problem with the alternator regulator.
