Don't do anything yet ! There is a huge variation in what the correct power supply should be. First, figure out what the coil resistance is, and report back here. The coil resistance will determine the required voltage, and if a series resistor will be required. Sometimes the resistance is indicated on the instrument. Also, if you can post a picture of the device here it may help.
