Thanks for the response. I don't have a working ICM to check. My idle is controlled by a home built controller using a PICAXE 14M2 processor. It uses PWM to control the ICV. I was just hoping someone had already checked the amps on one of these systems when the idle switch is open. My system works great at setting the idle speed but I don't know what it should do when it is not idling.
