4.3 Connecting The Power Wires
IMPORTANT :
Although the wiring loom in this kit was designed to work with either a
12 volt or 24 volt system, the DC motor of the compressor has been designed
ONLY for use on one specific voltage system.
Make sure you have the CKMA12 compressor kit for 12V systems or the
CKMA24 for 24V systems.
Connecting a compressor to an incorrect voltage level will cause extensive
damage to the compressor’s DC motor, so carefully follow the Power Connection
instructions below that apply to the vehicle.
IMPORTANT :
Never connect the power to the compressor while the vehicle key
is in the ACC position, as this may result in accidental compressor start-up.
4.3.1 Power Connection To A 12V Vehicle / System
F
Trim all 3 wires to the correct length for connection to the battery.
NOTE : If any of the wires require extra length to reach the battery then splice in an
extension using ONLY wire that is of the same gage or bigger than the wire
being lengthened.
NOTE : The inline fuse should be located as close to the battery connection as
possible. Never eliminate the fuse when shortening the RED wire, and only
ever lengthen the RED wire on the opposite side of the fuse from the
battery.
F
Crimp one yellow eye terminal (supplied) onto the heavy gage RED wire.
F
Crimp the remaining yellow eye terminal (supplied) onto the heavy gage black wire that is
marked with a white stripe (BLK-WHT).
NOTE : In a 12V system the 2 black wires (BLK and BLK-WHT) will be joined
together, so they may be crimped together into the same yellow eye
terminal if desired.
F
Crimp the blue eye terminal (supplied) onto the lighter gage solid black wire with no stripe
(BLK).
F
Connect the RED wire to the positive (+) terminal of the battery by securing the eye
terminal under the nut of the clamping bolt.
F
Connect both of the black wires (BLK and BLK-WHT) to the negative (-) terminal of the
battery in the same way.
F
Secure all loom wiring with cable ties along its entire path, as vibration could cause wear
to the insulation over time which could result in a dangerous electrical short.
