• 24 Volt Systems (2 Batteries)
• 36 Volt Systems (3 Batteries)
• 48 Volt Systems (4 Batteries)

24 Volt Systems (2 Batteries)

1. Two 12-volt deep cycle batteries are required.
2. Make sure that the trolling motor is switched to the off position or speed selector set to “0”.
3. Wire in series only as directed in wiring diagram, to provide 24 volts.
   1. Connect a connector cable to the positive (+) terminal of battery 1 and to the negative (-) terminal of battery 2.
   2. Connect positive (+) red lead (from motor) to positive (+) terminal on battery 2.
   3. Connect negative (-) black lead (from motor) to negative (-) terminal of battery 1.

36 Volt Systems (3 Batteries)

1. Three 12-volt deep cycle batteries are required.
2. Make sure that the trolling motor is switched to the off position or speed selector set to “0”.
3. Wire in series only as directed in wiring diagram, to provide 36 volts.
   1. Connect a connector cable to the positive (+) terminal of battery 1 and to the negative (-) terminal of battery 2.
   2. Connect a connector cable to the positive (+) terminal of battery 2 and to the negative (-) terminal of battery 3.
   3. Connect positive (+) red lead (from motor) to positive (+) terminal on battery 3.
   4. Connect negative (-) black lead (from motor) to negative (-) terminal of battery 1.

48 Volt Systems (4 Batteries)

1. Four 12-volt deep cycle batteries are required.
2. Make sure that the trolling motor is switched to the off position or speed selector set to “0”.
3. Wire in series only as directed in wiring diagram, to provide 48 volts.
   
   1. Connect a connector cable to the positive (+) terminal of battery 1 and to the negative (-) terminal of battery 2.
   2. Connect a connector cable to the positive (+) terminal of battery 2 and to the negative (-) terminal of battery 3.
   3. Connect a connector cable to the positive (+) terminal of battery 3 and to the negative (-) terminal of battery 4.
   4. Connect positive (+) red lead (from motor) to positive (+) terminal on battery 4.
   5. Connect negative (-) black lead (from motor) to negative (-) terminal of battery 1.
