1979 chev truck wont turn over

[c10 custom]

hi guys i have a 1979 chev truck was driving it and it quit and it wont turn over now the fusible link to the starter has power to it all the way to the junction block on the firewall to test to see if the starter solenoid is bad do you try and arc the big terminal to the small terminal and tried tapping the starter and there was no action out of it at all the lights come on and gauges move so im not sure if it could be the ignition switch or not any help would be great thank you
