I can, but sending the signal without the spark plug and wire you can hear it clicking just no very little juice coming out. Both banks are grounded straight to battery and to the ms3 board. Those coils are probably factory one, thinking these are cheaper versions, even factory ones are up in price to $75-$90/per I've seen on some and AC delco brand name

You shouldn't hear coils clicking. That's likely the coil output finding a path to ground. When I did my initial test, I had the plugs removed and put a ground jumper to the body of the plug. That way I could see the strength of the spark. It was also neat to see how adjusting the dwell changed the spark intensity.
