Starter or solenoid? Hot...no start $#@%&!

[55chevy]

Years ago I had a 74 Nova SS that was my daily driver and it would do that all the time. Even with a new starter after driving it awhile I'd shut it off and it wouldn't want to start. I just kept an old screw driver with me, when it would do that I'd turn on the switch, then reach down between the header with the screw driver and manually arc'd the starter terminals on the solenoid and it would start right up. After awhile that became a pain in the ass and I cured the problem by rewiring the starter switch with heavier gauge wire. No problems after that.
