Narrative:
During the takeoff roll; I noticed a yellow 'look up' light on the master warning panel. I looked up and the only light I noticed was an engine ignition light on the left side of the overhead panel. I looked back down and noticed the same 'look up' light was still on. I looked at the right side of the overhead panel and saw that another yellow light was on; indicating that the left inverter was offline. I pushed the rocker switch turning on the inverter; which activated a flashing red warning light. The pilot flying saw the red light and aborted the takeoff. We exited the runway; pushed the red light; which turned it off and taxied back to the beginning of the runway for takeoff. We could not duplicate the problem; it hasn't happened before and hasn't happened since. We took off without further incident for our destination. The only thing I would have done differently was to call for an abort of the takeoff; which happened anyway.
