[DML] Re: Idle Speed Motor / Cooling



You might want to jump further and go to "Fundamentals of Alternating
Current. A fluctuating DC is AC just with it's baseline moved up. You
can assume the coil to be a resistor but the #'s you come up with are
not going to be exact. When you test the coil on a battery it will be
with a steady DC so you can use the more simple DC calculations. They
will not work once you try to measure when the ECU is running the idle
motor.
