Default 78 Alarm System Problems

Need some help with my problem.
I parked my car this morning and when I locked the drivers door with the key the alarm horn was going off so I turned the key back to center and it stopped. When I came back to the car got in and tried to start it nothing. I've tried setting and unsetting the alarm by turning key to the left and then to the right nothing. Disconnected and reconnected the battery nothing. I tried starting the car in neutral nothing. I have interior lights, horn and headlights.
Any help would be greatly appreciated.
Pat
Update had nothing to do with the alarm battery shorted out.

I just was reading a post and it said that the 78 alarm does not disarm the starter. Does anyone know if that's correct? Does the alarm have any effect on the ignition switch?

In an effort to educate myself and help out a fellow forum member, I used the advanced search button and found the schematic and copied it to my computer and posted it.

Thank you for all the help you have offered over the years.
Regards, Pete.
