WIRING
If during maintenance or inspection, it becomes necessary to
move or reposition any of the engine’s wiring or wire harnesses,
verify that wiring is returned to its original position, and that all
harnesses are routed correctly. If a wiring clip or retainer breaks,
replace it immediately. Wiring is specifically routed to eliminate
problems related to engine heat and spray, immersion in liquids,
or contact with rotating assemblies. Electrical problems can result
if wiring is moved from its original position and is not properly
repositioned.

If you add high current accessories such as thrustors
or stereo systems, see your dealer for an Indmar High
Output Alternator kit.
Charging System Maintenance / Guidelines
Adhering to the following procedures and guidelines will ensure
proper operation of your battery charging system. Watch out for:
1.
REVERSE BATTERY POLARITY:
When reconnecting the
battery after winter storage, it is easy to accidentally reverse
the battery leads and connect positive to negative and
negative to positive. This generally results in a large arc at the
battery terminals and fail
ure of the diodes and/or regulator in
the alternator as well as other components in the electrical
system of the engine or boat that are polarity sensitive such as
ignition modules, ECMs, stereos, etc. For several components
to fail at the same time, the failures are generally due to some
external influence such as reversed battery leads or reversed
jumper leads. These types of failures are not covered by
Indmar’s Limited Warranty.
2.
POOR CONNECTIONS:
When there is a defective connection
between the battery and alternator, charging current will be
forced to find an alternate route to flow out toward the battery.
A defective connection may be caused by corrosion or an open
circuit from a break in several battery cable strands or simply
a loose connection. The alternate route that current finds
usually leads to excessive current flow, causing the diodes in
