Put your meter on regular resistance setting and meter the coil. Check its resistance against this chart:

It should be close to the values given there. If the exact coil isn't listed, look for a similar one in gauge and number of turns and it should be pretty much the same since wire resistance is a pretty steady value. For best results, it's probably good to have the coil out of circuit.
