    Anyone had their Cummins do this on start up? Truck was on high idle (approx 1100 rpm) and plugged in so not stone cold. Seemed to stop after I unplugged it. Not sure how that could effect it, thought it was just a block heater. Got the recall the other day for the alternator and wasn't sure if this was a sign it was on its way out.
