I had a fellow here in town re-wind some electro-magnets for some trafficators I have. He used a mathematical formula which takes into account the volts/amperage of unit, the need of volts/amps say for start up and running, THEN the amount of space you have in which to locate the unit THEN you can figure the diameter and length of wire required to handle and operate the unit. FOR example it took a little over 100' of small copper wire (I forget the diameter) to rewind the electo-magnets in my trafficators to have it operate properly for as low as 4 volts and up to the stock 6 volts of the system.
