ENGINE ELECTRICAL SYSTEM
Your engine utilizes a great deal of electronic equipment. Select
equipment sends signals between the engine and the Garmin, while
other systems set o alarms, and still others are used by the engine
to generate a spark and ignite the fuel. e battery switch controls
electrical power distribution to the boat systems.
To regularly maintain your DC electrical system, inspect the battery
charge before each trip. Test all gauges and control equipment
prior to departure, and replace as necessary. Spark plugs should
be replaced according to your engine owner’s manual maintenance
schedule. When a fuse blows, investigate the problem before
replacing fuse.
Gauge Electrical Signals
Your outboard transmits signals through electrical harnesses to
di erent components through the use of NMEA 2000 connections
and a “backbone system”. A standard Garmin plotter displays the
engine functions. e fuel gauge and power trim gauges use stand
alone technology to display readings. Also, idiot lights are display
tolerances that are classi ed as being abnormal. Faults in these
electrical components should be fully inspected by your Regal
dealer.
Alarms
When a malfunction with your outboard engine occurs, the Garmin
plotter alerts the skipper of a problem. Common engine problems
include overheating, low oil pressure, or a miscommunication with
equipment. Learn the alarm systems that apply to your engine by
consulting your engine owner’s manual.
