The correct way to determine the windings ratio for an unmarked transformer is to apply a known low voltage AC to the primary winding and measure the secondary output. The ratio of these voltages will be the same as the windings ratio. This method is safe and does not rely on potentially incorrect or non-standard wire color codes or resistance measurements, which can be misleading due to factors like wire thickness and material.
