if the 1A operates manually then i would check the accelerator , it has a switch in it that should make when the pedal is near 100% which calls for pulling in the 1A contactor.
open up the accelerator box and check that switch and all of its wiring, even the connection at the plug on the box.

one other consideration to make is the 1A time setting on card1.

if you want a manual that will help you with this try checking fsip.biz , they have one in the technical section under GE Technical Manuals.
