STARTER
WARNING
Accidental or remote starting can
cause severe personal injury or death. Before
removing an access door or belt guard, discon-
nect the negative (−) cable at the battery to pre-
vent the engine from starting.
The starter motor is bolted to the flywheel housing
(Figure 6-4). See the Engine Workshop Manual
(Table 6-1) for service or replacement. Parts are
available for rebuilding the starter. Torque the
mounting bolts to 29 lb-ft (39 N-m).
GROUND ISOLATION RELAY K9
When required, the genset is equipped with isola-
tion relay K9 (Figure 6-4) to isolate the negative (−)
battery terminal from the vessel grounding system
while the genset is running. (The engine block is
connected to battery negative [−] during starting.)
Replace the relay if its contacts do not close when
battery voltage is applied to the coil terminals.
