Yes have had parts checked and NAPA says they are working?
What problem do I have. It works and charges just fine as long as I remember to gun it to start it charging.
Stump the Stars??
My truck was doing the exact same thing after I replaced my alternator and external regulator. What finally fixed my was removing the ground wire near the regulator and cleaning the area under it to bare metal. That ground wire grounds the voltage regulator and the alternator. Once I hooked everything back up, it charged at idle. I hope this helps you avoid the hours I spent trying everything else.
