STARTER MOTOR CIRCUITS
Operating principle :
The starter motor requires two circuits.
1. Control circuît :
This consists of the following elements
connected in series:
Battery, fuse, key switch, stop
switches, starter motor relay, start
switch (START).
With the ignition key in the ON
position, one or both stop switches
closed, the start switch closed, the
current supplied by the battery runs
through the coils of the relay and
closes by magnetic force, the power
circuit contact.
2. Power circuit :
This consists of the battery and starter
motor.
Activated by the relay, this circuit
consists of big wires aimed at
supporting high intensity. This circuit
is not protected by the 1OA fuse.
Troubleshooting :
Checks in the event of non starting.
Battery in good condition.
If the relay «clicks», check the battery
connections, the starter motor
connector, earthing of the starter
motor, the starter motor itself.
If the relay does not «click», look at
the taillight:
. if the taillight comes on, check the
relay
. if the taillight does not come on,
check: the battery, fuse, key switch,
stop lights, connectons.
Relay is good and working order
Relay at of order
Checking the starter motor :
Connect the starter motor directly to
the terminale of a 12 volt battery.
Checking the relay :
Connect a battery to the terminale of
the control circuit (small yellow / green
and purple wires). If the relay is
working correctly, it will «click» and will
make contact with the two other
terminals.
