Question:

Can a dead alternator cause a car to stall at red lights?

But it turns back on after cranking it immediately(sometimesl). After a place like running in to grab food it dies and rapidly clicks. I‘m replacing the alternator tomorrow but can it cause stalling in the streets or is that something else

Answer:

If your alternator is dead your car will rely on the battery to spark the spark plugs (and everything else electrical), if that battery dies so will your car. Also, if your alternator is dead, then your battery will soon follow b/c your alternator is what keeps your battery charged.
Yes but it kills battery first then nothing will work like starter, fuel pump etc. Make sure to get battery recharged and load tested to see if good or bad first then get alternator checked, it's possibly ok if bat. bad and alt. can't keep battery up.
the motor is shotdead.call junkyard for price on replacement.some repair shops will charge you for installation only.the motors are NOT cheapcall around
I suggest you charge your battery tonight, and go down to the auto parts in the morning or whenever and have the charging system and starter checked by the auto parts store, they have a machine they can bring out, But as your battery gets discharged it gets worse and worse and to answer your question YES ITS POSSIBLE THE ALTERNATOR IS BAD
