The DC connections (continued)
3. You will also need to establish a path between the
charger’s common DC negative output and the common
negative (-) engine ground connection. This is normally
where the batteries’ negative cables connect to the engine
block. (When installing this unit in outboard powered
boats, the DC negative (-) charger output will be
connected directly to the negative (-) terminal of one or
both batteries.)
Do not connect any wires to the batteries or to the charger
until AFTER you have cut each one to size, crimped an
appropriate connector onto each end and securely mounted
the wires with the screw-downcable ties. This can help to
prevent accidental short-circuits during your installation.
4. After you have determined an appropriate path for the
DC wires to each battery, cut them to size, leaving three
feet extra. Strip 3/8” of insulation from the battery ends
of the red wires. Test fit a 5/16” ring terminal onto the
threaded positive (+) posts of your batteries. Remove the
ring terminal from the battery post and crimp or solder it
onto the battery end of the red wire.
5. Repeat step 4 for the red positive wire leading to the
other battery ‘s positive post~.
6. Repeat step 4 for the black wire, using a ring terminal
that will fit your engine’s negative ground terminal.
7. Use screw mounted cable ties or wire straps to fasten all
the wires between the batteries and the charger onto solid
surfaces. Avoid running wires over sharp edges or near
areas of extreme heat.
Remove the two screws on the lower face of the
expose the wiring terminals. The AC and DC
terminals are arranged as shown here:
