They should all be ~1000 Ohms. Your 2 & 4 look okay, but 1 & 3 seem 
oddly low. I've never seen them go low, so this is puzzling. Perhaps 
you should check them again. The actual value really isn't important; 
they eventually go open (infinite resistance) and that's when they 
need to be replaced.

The rotor should measure ~5000 Ohms from center to end. Some wire 
sets also include a special lumped resistor in the coil connection. I 
THINK that one is also ~5000 Ohms, but many wiresets lack that 
resistor and are zero Ohms for the coil wire.
