67 twin turbo dart

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
Curious on your wiring. Of the two coil grounds you have one going back to the MS sensor ground, and then the second going straight to the battery negative? I believe I’ve read about coil issues when wiring to the battery instead of directly to the engine block/head.
