BATTERY
1. When replacing, jumping, or otherwise connecting
the battery to the battery cables, the proper polarity
must be observed. Failure to observe the proper
polarity could result in damage to the charging cir-
cuit. The positive (+) battery cable has a red termi-
nal cover.
2. If the battery requires charging from an external
charger, disconnect the negative battery cable first
and then the positive battery cable before attaching
the charger leads. Failure to do so can result in
damage to the internal charger components. When
reconnecting the cables, connect the positive cable
first and the negative cable last.
