CONNECTING THE BATTERIES IN SERIES
positive voltage into the "ground" of that accessory, which can cause excess corrosion. Any damage caused by incorrect connections
between battery systems will not be covered under warranty.
Automatic Jump Start Systems and Selector Switches
Automatic jump start systems and selector switches tie the negatives of the connected batteries together. Connecting these systems to the
"High Side" Battery or "Middle" Battery in the diagrams below and will cause significant damage to your trolling motor and electronics.
The only trolling motor battery that is safe to connect to one of these systems is the "Low Side" Battery.
NOTICE:
The internal bonding wire is equipped with a 3 amp fuse. Improper connections described above carrying in excess
of 3 amps will blow this fuse and no further damage will be exhibited. If this occurs, RF interference from the trolling motor
affecting sonar units and other electronics will be more significant. If the fuse is blown the wiring error should be found and
addressed prior to replacing the fuse. The replacement fuse should be 3 amps or less. An intact fuse does not imply correct
rigging; significant damage can be done by incorrect wiring without approaching 3 amps of current.
CONNECTING THE BATTERIES IN SERIES
(IF REQUIRED FOR YOUR MOTOR)
24 Volt Systems
Two 12 volt batteries are required. The batteries must be wired in
series, only as directed in wiring diagram, to provide 24 volts.
1. Make sure that the motor is switched off
(speed selector on "0").
2. Connect a connector cable to the positive ( + ) terminal of
battery 1 and to the negative ( – ) terminal of battery 2.
3. Connect positive ( + ) red motor lead to positive ( + ) terminal
on battery 2.
4. Connect negative ( – ) black motor lead to negative ( – )
terminal of battery 1.
For safety reasons do not switch the motor on until the propeller is in the water. If installing a leadwire plug, observe proper polarity
and follow instructions in your boat owner's manual.
• For safety reasons, disconnect the motor from the battery or batteries when the motor is not in use or while the battery/batteries
are being charged.
• Improper wiring of 24/36 volt systems could cause battery explosion.
• Keep leadwire wing nut connections tight and solid to battery terminals.
• Locate battery in a ventilated compartment.
