does the air intake heater on a cold night cause my alternator and batterie to stay below 12 volt for about 45 sec. that cause my remote start not to run
x2 glow plugs, mine are off right now and it jumps right to 13.9 @ idle, i dont have a iah either, but it still delayed with that out and glow plugs on
I am interested in determining if there is a program charging delay under some circumstances. If that voltage stays depressed with higher idle speed, I believe that may be causing your observation.
