Start Circuit Operation
The starter must engage and turn the flywheel.
The outboard must crank a minimum of 300 RPM
to start.
Starter performance depends on the following:
•
Proper battery and cable capacity.
•
Clean, tight cable connections.
•
Solenoid activation through the key switch and
neutral safety switch.
Refer to
Predelivery and Installation Guide
for
battery, terminal, and cable requirements.
Solenoid Wiring
The positive (B+) battery cable connects to a large
terminal of the starter solenoid. This terminal also
provides the 12 V power supply to the engine har-
ness (red wire) and the 10 A fuse. The red/purple
wire from the fuse holder (10 A) provides 12 V to
terminal “B” of key switch.
The negative (B–) battery cable connects to the
main ground stud on the starter housing.
Engine Wire Harness
Contains the following circuits:
•
Red/purple output wire from fuse provides 12 V
to instrument harness.
•
Purple wire provides switched 12 V to
EMM.
•
Yellow/red wire provides switched 12 V to sole-
noid (terminal “A”)
.
•
Yellow/green wire provides ground (NEG) to
starter solenoid (terminal “B”).
Instrument Wire Harness
Contains the following circuits:
•
Red/purple wire provides 12 V to key switch ter-
minal “B”.
•
Purple wire provides switched 12 V to engine
wire harness.
•
Yellow/red wire from terminal “S” of key switch
provides switched 12 V to solenoid (terminal
“A”) (key switch in START position).
Key Switch, ON position
12 V is applied to the accessory circuit. Key
switch ON:
•
Switches 12 V to terminal “A” of key switch and
to the purple wires of the wire harnesses.
•
Provides 12 V input to terminal 28 of
EMM
J1-B
connector.
EMM
turns ON.
Key Switch, START Position
Key switch START:
•
Switches 12 V to terminal “S” of key switch and
to the neutral safety switch (in remote control).
1.
Key switch, ON position – Continuity between ter-
minals “B” and “A”
2.
Terminal “B”, 12 V (Red/purple)
3.
Terminal “A”, 12 V (Purple)
