the exciter coil has no secondary, I suspect you are referring to the ignition coil.

the ignition coil primary .3 ohms, secondary ( without plug caps) 8.6 K ohms
pulser coil 207 ohms.
plug caps 4.2 K ohms and 4.5 K ohms.
oil pressure switch opened at about 3.5 psi.
all interconnecting wire checked point to point good.

considering the value for the exciter coil you provided I intend to change the CD unit to correct the problem.
