Connect one end of Jumper Lead #1 to Simple SCR/Triac Tester - Cathode Terminal and the other end to the Positive Terminal.
Connect one end of Jumper Lead #2 to Simple SCR/Triac Tester - Anode Terminal and the other end to the AC Terminal.
At this point check the Test light on the Simple SCR/Triac Tester unit.
If the Test light is not glowing, then proceed to Step 2.
If the Test light IS GLOWING the Half Bridge Module is short and should be replaced.
Now connect one end of Jumper Lead #3 to the Simple SCR/Triac Tester - Gate Terminal and the other end, you will just touch the Gate Terminal (the smaller tab on the outside) and then remove it.
At this point check the Test light on the Simple SCR/Triac Tester unit.
If the Test light is NOT glowing or just flashed as you touched the gate wire, you should replace the Half Bridge Module.
If the Test light is glowing, then the Half Bridge Module is good.
