Narrative:
On takeoff roll immediately after N1 reached full power; 90%; the mc light illuminated along with ovid cowl-anti ice amber light on left engine. We aborted the takeoff and cleared runway. The light extinguished immediately with reduction of power. Airspeed achieved was less than 40 kts. I decided to run up the engine to see if it was temporary flicker or if it was a true overpressure in the cowl anti ice system. We did a static run up of left engine; with clearance from ground; to 80% N1. The light remained extinguished. I decided to return for another takeoff. Unfortunately; this takeoff ended in an abort as the cowl ice amber light illuminated at 85%.in hind sight; we probably should not have even done the run up and just returned to the gate. Even if I wasn't sure if it was a temporary flicker of a light; reintroducing high pressure to the cowl was probably not the safest choice.
