Installing the battery

• Improper battery connections or cable size selection may result in a fire.
• When installing an isolator lead to the positive battery terminal or battery switch, over-cur-
rent protection in compliance with ABYC (E-11) must be provided.
If battery connections are reversed, thorough charging system testing is required, replace
damaged components. See "Charging units and components" (5-26).
See "Rigging recommendations" (3-25) for the extension battery cable length.

Battery wiring without house (accessory) battery

• When only one battery is used for one engine, connect the positive battery cable and the
isolator lead to the positive battery terminal. If the isolator lead is left unconnected, acci-
dental contact of the isolator lead with the negative terminal of the battery can cause a
short circuit which may result in a fire.
• When using a dual battery installation, a negative battery cable must be installed between
the both engine batteries. This cable must be sized equivalent to the engine battery cables
or larger AWG cable size in accordance with ABYC specifications.
