Bob, as you know Im NOT an IHC Mag man buttttttt I'm learning n think your post was great. A typical Mag primary may be only like 0.5 ohms so I sure agree it appears almost a short on either the open (to points) end or the grounded end. At my Wico talks I tell em to use a good ohmmeter set on the R x 1 scale with a lead to ground and the other to the points and when closed it should read near zero ohms but when open still only like 1/2 to 1 ohms or so. If an open its obviously an open coil primary but if it stays a dead 0 ohms short even with the points open, I tell em to suspect a bad/shorted condensor (unhook n try it) or the points spring may be shorted or the point to coil wiring etc. has a short.

I may get an IHC Mag n play with it lol
