thanks, i checked the pot and did see one small difference between the stallind one and the good runner,when i am observing the stalling one i see a real fast ol(over load-meaning an open ckt) when i cycle the pot. if i stop anywhere i can never get the ol to read again,just when its in motion.
we use wire wound pots in the scale business and its common to see the open when cycling the wiper.
i suppose i could replace the sucker to prove the point.
i was looking at the values across the idle control valve today and accidently left the vom on an and saw that it had 6vac across the supply. does the n3 controller have a pulsed output to the idle control valve?
thanks larry perkins
