Service Precautions
The following requirements must be observed:
•
Before removing any ECM system component, disconnect the negative battery
cable.
•
•
Never start the engine without the battery being solidly connected.
Never separate the battery from the on-board electrical system while the engine is
running.
•
Never separate the battery feed wire from the charging system while the engine is
running.
•
•
When charging the battery, disconnect it from the boat’s electrical system.
Ensure that all cable harnesses are connected solidly and that battery connections
are thoroughly clean.
•
•
•
Never connect or disconnect the wiring harness at the ECM when the ignition is
switched ON.
Before attempting any electric arc welding, disconnect the battery leads and the
ECM connector(s).
When steam cleaning engines, do not direct the steam cleaning nozzle at ECM sys-
tem components. If this happens, corrosion of the terminals or damage of compo-
nents can take place.
•
•
Use only the test equipment specified in the diagnostic charts, since other test equip-
ment may either give incorrect results or damage good components.
All voltage measurements using a voltmeter require a digital voltmeter with a rating
of 10 megohms input impedance.
