PRODUCT INSTALLATION, WIRING, AND BATTERY
5. Connect a jumper cable (common ground bond) from the trolling motor
battery negative (–) terminal to the engine battery negative (–) terminal.
NOTE: Vessels using 12‑volt trolling motors with multiple batteries must have
a common ground bonding circuit. Not establishing a common ground
between the vessel batteries may cause severe corrosion, electrolysis, or
electrical shock.
NOTE: The common ground bond cable should be no more than one wire size
(gauge) smaller than the battery cables, nor smaller than 16‑gauge (AWG).
The common ground bond cable must be insulated, and secured to the
negative (–) battery terminals with ring‑style connectors.
6. Starting with the positive (+) lead, reconnect the battery cables to the
engine starting battery.
