no light when we do this. what does that mean. also put the tester in tack mode and nothing happened grounded with the positive on the coil but the tachometer( in dash) just barely moves when cranked

I am not great at reading wiring diagrams, but it looks like there is a fusible link in there between the ignition switch and the coil(Haynes manual). I had a deal like this a couple years ago with a '90 Ford Taurus, the Haynes manual for that also showed a fusible link but I couldn't find it for the life of me(it must have been wrapped in tape at the factory along with a bunch of other wires. I had already determined that the ignition switch was good with a test light, so I just ran another wire to the coil. If this turns out to be your problem don't cut any wires just splice into them so the alternator will still charge(that's another story).

No the EEC Relay is not between the Ignition Switch and the Ignition Coil.

On my 90 f-350 the fusible link for the ignition was in a harness on the right side between the battery and the fender wall. The ulitimate failure was a green and yellow wire in the harness connection on the drivers fender wall. Had power on the side from the switch but nothing on the other side. Looking at the diagrams from "Data Research by Automotive Hobbyists" all 1990 models are the same. Hope the 1989 is too or you can download schematics from them.

He also said the engine cranks so the fuse link is good that feeds the Ignition Switch.
