The only explanation for it is your coil is touching something it shouldn't be or you have a piece if wire inside your deck from clipping your leads so take a coil out check for random bits of wire and see what 1 coil reads at
Don't know the ID of the coil, but a quick check on steam engine would suggest each coil should be approaching 0.4 ohms, giving circa 0.2 for the pair. Definitely something shorting.
