wiring grimlins

so i purchased a 83 FB that had a 6 port 13b swapped into it, motor is streetported and ran pretty damn good in the rx2 sedan it was in. kid swapped the motor in and never started the car and later down the road i buy the car. we put a 13b dizzy in the car and it fried both ignitors and refuses to start, wired up some GM ignitors but still am not getting any spark. i double checked my wiring but still nothing.
any ideas?

Had a chance to look at your drawing closer & appears you have wiring from module to coil backwards. In your drawing you have module terminal B labeled as C & C as B. Ignition primary 12 volts should go to terminal B on module And terminal C on module goes directly to ig. coil negative terminal. Both modules appear to be wired the same, change B & C orientation on modules and you should have spark.

so turns out i had everything correct after checking a few things and doing what you had suggested. nothing worked and the car was deemed a total loss. i put the motor in my other FB and it fired up instantly
