Wow, I could really use some help with this as well. I have an 83 odyssey with a weak yellow spark. I can hold the spark plug while I pull the recoil and although I can feel the spark, I don't have to let go! I have replaced the spark plug coil, pulled the flywheel and checked and cleaned the magnet and stator - but no luck:(. Anyway, VooBoo I can help with some of your questions. I think in 1981 the oddyseys went to a cdi capacitor discharge ignition. Earlier models used points. I hope someone will suggest a better test for the stator coils. For the lighting coil do an ohm's test between the yellow and green wires (my reading is 1), Exiter coil - test the Black/red and green wires look for resistance of 245 +/- 20% (My reading is 198.5). Pulse coil check blue/yellow and green stator wires, resistance of 20 - 60 ohms My reading is 30.7) Both old and new spark plug coil test primary 0.2 - 0.8 Ohms (mine is 0.4) and also test the secondary coil which should be 8000 - 15000 ohms (Both old and brand new coils read 1 which is open) Either the specs are wrong or both old and new coil give same reading or I'm doing something wrong. Hopefully, Someone much smarter than me can give us a better way to test ignition and stator coils. Thanks again.
