ENGINE STARTING CIRCUIT
OPERATION DURING START PROCESS
When the starter switch is turned to the start position, the safety relay (14) is opened by the current flow
from the connected "52" and "67" terminals of the transmission controller (13) and the "S" and "E"
terminals of the starter controller (7) are connected. At this time the contacts in the starter relay (8) are
closed by the current flow from the battery (1), to the fusible link (3), to the "B" terminal of the starter switch
(5), to the "C" terminal of the starter relay (8), to the "D" terminal of the starter relay (8), to the "S" terminal
of starter controller (7), to the "E" terminal of the starter controller, and then to the ground.
When the contact point "B" and "PP" of starter relay (8) are connected, the pinion gear of the starter (9) is
pushed forward and makes contact with the ring gear of the flywheel and the internal contacts of the starter
are connected.
The current flows from the battery (1), to the "A" terminal of the battery relay (2), to the "B" terminal of the
battery relay (2), and then to the "B" terminal of the starter (9). The starter motor is rotated and the engine
is started.
The engine can be cranked only when the transmission selector switch (11) is the neutral position. If the
transmission selector switch (11) is in forward or reverse, the current that flows the switch (11) to the starter
controller (7) opens the path to ground for the starter relay (8). This prevents the starter relay (8) from
closing.
