(4) Check the wiring through ZCT on the IDLE
CONTROL UNIT BOARD.
A) Single Voltage Type
Make sure that an output wire from main coil
is passing through the ZCT on the IDLE
CONTROL UNIT.
B) Dual Voltage Type
Check that two output wires (black wire and
red wire) from main coils are passing through
the ZCT on the IDLE CONTROL UNIT in the
same direction.
