I checked continuity at exactly the locations indicated in the attached image. All good. Not shown, I also checked the cluster from pin B to the end of the ammeter trace and from from pin E to the end of the ammeter trace. Both good. I should have checked voltage for grins but think about it. It's too hot out now so I'll so that Tuesday morning.
I made a poor choice of size in scanning the book. The image is hard to read at the reduced scale. It it's a problem I redo it.
I'm still puzzled as to how the traces could have burned in-two. The shunt shows to be intact.
