Got spark on on positive side of wire feeding coil. No light on, ground side no power to coil, no spark. Does anyone have the wiring diagram for under the hood? It looks like I am going have to rewire as a lot are just brittle and breaking. Any help would be awesome. Haynes manual is no good.

If there is no light on ground side it is either an ignition problem or bad coil. Coil should have 80-100 ohms on primary and 7600-14,200 ohms secondary. See pictures on how to check transistor.
