Are these two ignition coils interchangeable?
I mean, will an M20 coil run ok in an M10 engine? They look identical, and on paper, the resistances are different, but in the same ratio.
The primary / secondary on the M20 is 0.50 ohms on the primary to 5000/6000 ohms on the secondary.
The primary / secondary on the M10 is 0.82 ohms on the primary to 8250 ohms on the secondary.
I need to know really quickly!
