If a test lamp on the coils output (to distributors points) never flashes off with ignition on and engine cranked slowly, that means that point closure is NOT providing a good low resistance ground path...…….. Causes may be points are not fully tightly closing or burned or corroded or oxide coated (try to clean or replace) or the wirers open from coil to points. If only oxide coated a light not overly abrasive clean/buff/polish might cure the problem.
