      I unscrewed the coil and screwed it back in upside-down for testing.

      So far, I've got zero readings from the multimeter test. Here's the one I'm using:

      7 Function Digital Multimeter (at https://www.harborfreight.com/7-function-digital-multimeter-63604.html )

      The wires are in the two lower slots. I tried each one on the ground and each prong; each time the display remained zero, although once, a minus sign came up. Setting was DCV 200.

      I think I replaced the ASD relay more than 2 years ago, but that may have been another relay.

      Do you have the factory service manual for a 1992 Dodge Dakota? You can look in the wiring diagrams for ignition coil and it will give an image of the positive and negative terminals and wiring colors to each. On a 1991 model the positive coil terminal is a gray wire / black tracer.
      Yes, I went through dozens of pages of diagrams without finding one for the coil. In mine, one wire is mainly black, the other is mainly green.

      To measure primary and secondary resistance, you need to turn the setting to the 200 ohm scale, not 200 volts. You measured voltage, which is zero. For AllanC's tests, you would use the voltage scale.
