Can this test with the Ohms be done with the coil not installed? Ie it removed from the machine and the red & black leads on each lug, set to ohms?

Would this test work? Ive got a bucked of old coils and not sure which are good are bad

Just a question, i am testing a Gottlieb A-25959 and not sure on the reading i am getting.

with the base upside down so that i am looking directly at the back of the lugs, i am getting the below results with the "x" representing which connection is on each lug

x.......x
[] [] [] = .201 Mohm

x..x
[] [] [] = .197 Mohm

....x..x
[] [] [] = 3.9 Mohm

Based on this is the coil dead? Confused as getting different readings pending which lug i have the lead on. The coil is completely disconnected from the machine.
