Open all EOS switches and try again.
Just put a piece of paper between them.
I've had this kind of problem with Joker Poker.
Right flipper was good and the left flippers were both bad, or so I thought.
I opened both EOS and measured again and now all is good.

It looks like your coils are wired correctly.
I'll attach a part of the schematic.

You are measuring the resistance of two coils in paralel.
That means the resistance measured is devided by 2.
Lets say each coil is 40 ohms, the replacement resistance is 20 ohms for two coils paralel.
Sorry, just physics.
To truely take a good reading you need at least to disconnect each double power wire at the coils.
The outside lugs should be around 40 ohms and the thick wire winding should be around 3 ohms.

If you are missing a 3 ohm measurement that coil would not activate, as it's missing the power winding.
That is why you are seeing the 3 ohm at the left coils (with one bad power winding) and the lower 2 ohms at the right coils (4+4 in paralel results to 2 ohms).

Also at the flippers there is a double stack of switches.
Each flipper, which is activated by the cabinet button, has this.
If that flipper isn't working, the other is not activated, resulting in two flippers not working.
