Battery Connection
!
CAUTION
Disconnecting or connecting the battery cables in the incorrect order can cause injury from electrical shock or can damage the
electrical system. Always disconnect the negative (‑) battery cable first and connect it last.
12 Volt Battery Connection
1. Install a 50 amp manual reset circuit breaker in line with the trolling motor power cable positive (+) lead and the battery positive
(+) terminal.
2. Connect the black trolling motor power cable negative lead to the engine battery negative (–) terminal.
3. Connect a jumper cable (common ground bond) from the trolling motor battery negative terminal to the engine battery negative
terminal.
NOTE: Vessels 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.
