The 1-AD is a driver for the 1A to send a negative to the coil for 1-A contractor
All of the contractors will have a constant positive ( battery volts ) the card sends a negative to close them the thermal protector
If it is an ev-1 will be mounted on scr 1 it will have two wires that go to card you can jump the two wires and see if it moves make sure it is the thermal protector though there are two types of thermal protectors one will screw into scr 1 and one will have a screw that holds it on the scr 1 look up thermal protector on ev 1 on google it should show a picture of it
Your card has two sides right and left. As you request certain
Functions the input will go into card and the card will send a negative to selected component there is also ,which you will see on diagram , a pmt driver , that is a safety driver
Pulse monitor trip if there is stuck contact etc card will not allow unit to move or. Contacts to close
Again make sure you have the thermal protector it is on the unit to prevent it from moving in case the motor or scr unit gets too hot it will allow the contacts to close but will not allow scr control to turn on which in turn causes motor rotation
