Battery installation

• Make sure to connect the battery properly and select the proper cable sizes. Otherwise, a
fire could result.
• 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.
Do not reverse the battery connections. Otherwise, the charging system could be damaged.

Battery wiring without house (accessory) battery

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