battery load tested fine .had 14.0v at idle. esp no on as well ,bad diode in alt ? please advise thank you

 

I would suggest that you do a a alternator load test. Sometimes you can have the pressure (or voltage), and no have the flow (or current). Does the car shut off do to insufficient power, or is it just a battery light on.

 

started checking , main feed wire ((blue ) from alt plug was broken , wasnt feeding the other circuits properly.
