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.
HS125 pilot reports noticing a yellow 'look up' light on the master warning panel during takeoff. Another yellow light on the overhead panel indicated the left inverter was offline. When it is selected on the red master warning light begins flashing and the flying pilot rejects the takeoff.
