TP-6953 7/19154 Section 9 Component Testing and Adjustment
possibility of carbon monoxide poisoning. Seek medical
attention if the condition of affected persons does not improve
within minutes of breathing fresh air.
Inspecting the exhaust system. Carbon monoxide can
cause severe nausea, fainting, or death. For the safety of
the craft’s occupants, install a carbon monoxide detector.
Never operate the generator set without a functioning carbon
monoxide detector. Inspect the detector before each
generator set use.
Operating the generator set. Carbon monoxide can cause
severe nausea, fainting, or death. Be especially careful if
operating the generator set when moored or anchored under
calm conditions because gases may accumulate. If operating
the generator set dockside, moor the craft so that the exhaust
discharges on the lee side (the side sheltered from the wind).
Always be aware of others, making sure your exhaust is
directed away from other boats and buildings.
NOTICE
Electrostatic discharge damage. Electrostatic discharge
(ESD) damages electronic circuit boards. Prevent
electrostatic discharge damage by wearing an approved
grounding wrist strap when handling electronic circuit boards
or integrated circuits. An approved grounding wrist strap
provides a high resistance (about 1 megohm), not a direct
short, to ground.
9.1 Controller Handling
The controller contains an electronic printed circuit
board (PCB) that is sensitive to a variety of elements and
can be damaged during removal, installation,
transportation, or storage. Observe the following when
working with the controller.
9.1.1 Handling
D Don’t bend or drop the controller or any of its
components.
D Don’t strike the controller or any of its components
withahardobject.
D Clean a dusty or dirty controller only with a vacuum
cleaner, dry brush, and/or aerosol spray cans
specifically for electronic equipment and
components. Aerosol spray cans are typically found
with computer supplies.
D Never attempt component-level circuit repairs as this
may void third party certification.
D Never remove or install a controller with the power
connected.
D Label wiring when disconnecting it for reconnection
later.
D Remove wiring harnesses with plug connectors by
pressing the locking tab(s) and pulling on the plug
straight out to remove the wiring harness plug from
the controller socket.
D Use caution when removing a controller in a
paralleling system. If another generator set is
running, the controller’s harness pins may be
energized.
D If the start signal to a paralleling system is only
provided to one controller, consider using the
emergency stop instead of cycling power on the
controller otherwise the entire system may stop.
Pressing the AUTO-RUN on another generator set
before cycling power avoids this situation.
9.2 Other Service Parts
The removal and installation of service parts is covered
by the following generic procedure. Service p arts
include plug-in relays, switches, lamps, meters, gauges,
brackets, and other hardware.
Accidental starting.
Can cause severe injury or death.
Disconnect the battery cables before
working on the generator set.
Remove the negative (- ) lead first
when disconnecting the battery.
Reconnect the negative (- ) lead last
when reconnecting the battery.
WARNING
Disabling the generator set. Accidental starting can
cause severe injury or death. Before working on the
generator set or equipment connected to the set, disable the
generator set as follows: (1) Press the generator set off/reset
button to shut down the generator set. (2) Disconnect the
power to the battery charger, if equipped. (3) Remove the
battery cables, negative (- ) lead first. Reconnect the negative
(- ) lead last when reconnecting the battery. Follow these
precautions to prevent the starting of the generator set by the
remote start/stop switch.
