1993 Ranger XLT 2.3 ... 281k Miles
Last year or so, when the AC or Defrost is on, I lose significant power to engine when idling at stop or downshifting from 3->2 and 2->1 at stop. I recharged AC recently but same issue. You see a big drop in voltage and the engine will stall, or come close to stalling out completely. Shop tested alternator (5 years old) and says its fine.
If I am driving, at any speed, there is no issue. Its only when idling or downshifting that I experience this big voltage drop. (you see the needle drop to zero)
What is next step to investigate/remedy this situation?
