Connecting the WiMEA Signal wires
Before connecting the Boat Unit Signal wires,
you must test which kill switch principle is used
by your engine manufacturer.
The engine signal wires on WiMEA Boat Unit consists of three wires.
Only two of the three wires are used to connect to the existing kill
switch wires in your boat. Below are instructions on how to test which
of the Boat Unit signal wires to use and how to connect them to the
existing wires in your boat.
Overview of the Boat Unit signal wires (see picture on page 30 for
overview of the signal wires):
1. Common – Grey – Always used when
connecting the WiMEA Boat Unit Signal wires.
2. Normally Open (NO) – Blue – Used when your
existing system is a Normally Open kill switch
system.
3. Normally Closed (NC) – Orange – Used when your
existing system is a Normally Closed kill switch
system.
NOTICE
The engine kill switch system principle varies
across different engine manufacturers, and
different year of model, being Normally Open or
Normally Closed principle. Some existing kill
switches has three wires, you still only need to
connect two as described in this manual. The
principle in the existing mechanical kill switch is
the same as the Boat Unit Signal wires, where the
three wires makes the existing kill switch
compatible with both Normally Open and Normally
Closed kill switch systems
The existing kill switch system in your engine is either:
1. Normally Open (NO) – meaning that the kill switch opens and
disconnects the conductive latch to stop the engine.
2. Normally Closed (NC) – meaning that the kill switch closes and
connects the conductive latch to stop the engine.
The existing kill switch system has two wires, which are connected
to the mechanical kill switch (the switch to attach the standard red
cord), mounted in your helm, in the throttle quadrant, on your engine
or other suitable place near the driving position. To connect the Boat
Unit Signal wires you must first cut and strip the existing kill switch
wiring as shown on the picture below:
After stripping the two existing wires, proceed to test the kill switch
principle, as described below.
See page 39, Wiring diagram for overview of the wire
connections.
NOTICE
The grey wire on the Connection Cable is the CMN
(common wire) and is used to connect to one of
the existing engine kill switch signal wires,
regardless of the existing kill switch principle.
