Just wondering when you say  13 then 18? is that voltage or resistance & what scale on the meter? I hope you mean voltage but again what scale are you on?

I don’ know much abou the BIM ignation except it needs a component to “fire” the coil which I don’t see. It could have a threashold voltage for firing though,

Try measuring resistance from the spark plug wire, secondary winding to ground in a static mode on the x’s 1000 ohm scale for starters. I don’t know if it’s the photo but the two coils look different? Did you replace both coils or just one? I get the assumpion there is too many wires going to ground also. Can you post the diagram recieved withe replacement parts please? No capacitors too? That may be the firing component too when the cap reaches saturation it discharges to fire the coil? Not sure.
