A method of measuring current in a pulse count positioning system is provided, wherein various motor conditions such as back up due to cogging and/or gear train affects are taken into account in measuring current pulses that are correlated with the position of an electric device such as an automotive accessory. The method generally includes measuring current flow through an electric motor at regular intervals, summing the current flow at a second interval, storing the summed current flow as a current pulse occurs, starting a new sum of the current flow, and comparing sums for a previous two sums after a maximum timeout. Accordingly, the method according to the present invention takes various motor conditions into account for a more accurate measurement of current pulses, which correspond with the position of the electric device.
