Accidently posted my problem here please help

I'd get a DMV and start checking stuff. If ya lost spark to both plugs,I doubt its the coils. its a '78 so, CD ignition ? or points?

Since you say it lost it on both plugs I would start by disconnecting the black/yellow wire and see if the spark returns. The black/yellow is the wire that would run to a kill switch if equipped. If you have the kill switch then disconnect the ground side of it. If this works then check with the switch with an ohmmeter to see if it is closed. If it is then it has failed.
If not just look for it in the power pack harness and separate the harness connectors and gently pull that wire out of the connector. Push the wire connector at the same time so you don't damage it. If it runs at this point you either have a short on that wire somewhere or possibly a pack issue on that circuit. That wire carries 300V so don't touch it while running.
