INSTALLING THE MK-EC EXTENSION CABLE ACCESSORY
The Minn Kota Battery Charger Output Extension Cables are ideal for extending charger output cables that do not reach bow,
center or transom battery compartments. Featuring easy installation with waterproof adhesive heat shrink for use in saltwater
environments. Each conductor is fused for protection against accidental short circuits.
TOOLS AND RESOURCES REQUIRED:
• Wire Cutters
• Crimpers
• Wire Strippers
• Heat Gun
1.
Remove AC power from your charger and disconnect the charger from
ALL batteries.
2. Open the door or hatch of the compartment and allow it to air out
for 15 minutes. This allows any gasses that have accumulated in the
compartment to escape.
3. Find the charger output cable you would like to extend and use the wire
cutters to cut the red or white (positive) and black (negative) wires before
the fuse holders.
NOTE: Some output cables will have a temperature sensor in the cable
covered by heat shrink. You must cut above the temperature sensor to
avoid damaging the sensor (see Figure 1).
4. Remove the loose pieces of insulation from the ends of the extension cable wires and crimp the black (negative) wire into the
Wire Splice connector using the crimpers (see Figure 2).
5. Strip the charger output cable wires 3/8" if they are 12AWG. Strip the output wires 3/4" if they are 14AWG or 16AWG.
6. Place one of the Adhesive Heat Shrinks over the Wire Splice and onto the black extension cable wire.
7.
For 12AWG wire, insert the black charger output cable into the Wire Splice and crimp using the crimpers. For 14AWG or
16AWG wire, fold the stripped black charger output wire in half before inserting and crimping the wire.
8. Center the Adhesive Heat Shrink over the Wire Splice. Using the heat gun, warm the Adhesive Heat Shrink until it seals the
connection.
9. Repeat steps 4 through 8 for connecting the red or white (positive) wires to the Wire Splice.
10. Prepare each battery in advance by cleaning off dirt, oil, battery corrosion, etc. Use a water and baking soda solution for
cleaning corrosion. Wipe using a dry cloth.
11. Route the output extension cable away from sharp objects. Do not remove the fuse holders, since fuses are located on both
the positive and negative wires for protection in case of a short circuit.
12. Now connect the extension cable to the battery. Be sure to connect the black (negative -) ring terminal to the negative battery
post and connect the red (positive +) ring terminal to the positive battery post.
