CIRCUIT BOARD AND WIRING
Two (2) black wires are connected to "E" on circuit board. One goes to each "E" terminal of A and
FG circuit boards. In this case, the coding system is as follows:
Color of wire.
Number of stands contained in the core.
Circuit board
(In case of 8 cores, the number is not shown.I
