Finer wire and more turns mean higher resistance
Across the chart, a higher AWG number (thinner wire) and more turns give a higher resistance and a weaker pull at the same voltage: a 23 AWG, 800 turn coil reads about 4.2 ohms, a 27 AWG, 1300 turn coil about 14 ohms and a 34 AWG, 3000 turn relay about 120 ohms. Never fit a lower-resistance coil than the original without checking the driver and fuse can take it.
