Out of the blue, I turned the ignition key and the started jerked and stopped. Next turn solenoid clicked only. After that no sound on turning key.. No radio, panel lights, headlights, etc.

My guess at this point is that there is a bad negative ground.

No ongoing symptoms before today. Battery is new and checks out as fully charged. Voltage OK at the solenoid relay on the inside wall.

Searched last night for a main fuse or fusible links. Wiring diagrams show them but do not tell where to look for them. I assume close to the battery -- will spend some time now looking and TS with a meter.

Any other suggestions? Thanks in advance.

They will be (typically) some sort of little black box mounted on the firewall, or somewhere near the main fuse box or battery, it may look like a fancy connector as well. But it will be there. There will be no such thing on the ground side. Only on the + side.
