Figure 5: Ensuring a good wiring connection
Crimp both wires to the butt splice using
single-indent type crimpers. Fold the cable over
before inserting into the butt-splice as required.
Single-indent crimpers should also be used on
any lugs used.
Solder the wires to the butt splice. Ensure that
a good connection is made.
Keep heatshrink away until after soldering is
complete and has cooled.
5.5 AUXILIARY BATTERY POSITIVE — BROWN WIRE
The BROWN wire should be connected to the
auxiliary battery positive terminal of the auxiliary
battery.
Ensure the cable length is at maximum 1 m
(3.9') from the Unit and the MIDI fuse is
mounted in within 100 mm (3.9") of cable length
from the auxiliary battery. See "Specifications"
on page 5 for appropriate size fuses.

5.6 COMMON GROUND — BLACK WIRE
The BLACK wire should be connected to a
ground point that is common to both the start
battery and the auxiliary battery to be charged.
This point may be on the chassis of the vehicle,
on the chassis of the trailer/camper/caravan
or directly wired to both batteries, depending on
your installation requirements.
