MotorGuide BATTERY CHARGERS - Manual (Page 10)

When connecting each jacketed battery charger cable, make sure it is connected
to only one 12 VDC battery and observe the polarity and color of all connections:
Red Wire = + (Positive) Battery connection
Black Wire = - (Negative) Battery connection
The black wire can never be connected to a terminal with red wires. Only black.
Important: The pair of red and black wires in 1 cable jacket MUST GO TO THE SAME 12VDC battery.
Each charger cable must
be connected to 1 battery,
just as shown. Observe
black to (-) and red to (+).
Do this for each battery.

If only two batteries are used with a 3 bank charger, then connect the unused output
cable to either one of the two batteries, as instructed in item 8 above
Always connect each charger output to a single 12V battery even if the batteries
are wired series for 24V or 24V with an engine battery.
