(2) Return power within the J-3513 pin C is also applied through K5
to J3 pin H, through the CX-13061/U to the KY-57 pin N to ground.
additional ground returns to pin G, through the CX-13061/U, to J3 pin A.
When the grounds are completed, K5 energizes and K5 contacts close.
applies voltage to J2 pin B through CX-13063/U, to the HYP-57 and KY-57
power supplies (Figure 43). (Trace these circuits on your system diagram.)
Return power to the J-3513 and KY-57.
