coils come in 3 types, but I doubt you'll have the old 250ohm coil

put your multimeter on ohms (2K scale or lower) and measure between the blue wire of the coil to ground (or black wire) - it should read within 40ohm of either 350 or 450 (only the newest coils are 450ohm coils)
 
there is a soldered connection at the top of the coil that sometimes goes bad, but can be resoldered

try to test from the blue wire to the tiny bit of copper wire at the top of coil - if it reads good there, you can resolder that connection
