Installation Instructions
wire to the starter post as the voltage drops excessively
at this location during starting.
Batteries
Tapered post connections with wing nut connections
can be used. The tapered posts must be used for the
engine battery cables while the wing nut connections
should only be used for accessories. We highly recom-
mend that wing nuts be replaced with regular nuts to
increase the tightness of the connections.
Pay particular attention to ground connections. EFI
engines are very dependent on secure ground connec-
tions. See typical ground location.
Dual Engines
Batteries: Vessels with twin engines should have a
battery for each engine. The battery switch should be
positioned so each engine is running off its own battery.
Battery Isolators
Many boats are equipped with auxiliary batteries. Such
batteries are used to operate stereos, etc. Battery
isolators can be used to charge an auxiliary battery. In
these cases, the alternator output is connected to the
center post on the isolator instead of the starter. The
owner should familiarize himself with the isolator’s
operation.
