10.2 Replacement of Damaged Power Connectors
In some battery types, the battery is provided with a special quick disconnect receptacle,
such as a type manufactured by Elcon or Cannon, or any of a number of MS type
receptacles. Should one of these become damaged, it will be necessary to replace it with
a replacement part obtained from your local MarathonNorco authorized distributor. Care
should be taken in the removal of this connector to preserve all the hardware and
gasketing, if possible, so that the new part may be installed properly.
To remove the connector, first remove those connections which go to the end cells in the
battery, thus reducing the possibility of a short circuit when the connector body is
removed from the battery can. All MarathonNorco batteries have the same hardware
arrangement for attaching the power connector to the battery as is used on the intercell
connectors. When installing the replacement part, it is necessary to consult Table 2 for
the torque values.
CAUTION: Use only cells, intercell connectors, power connectors and all other battery components that are
specified on the battery parts list for your battery. Failure to do so will result in imbalances between
the cells within the battery and could create a safety of flight issue.
