Step 3
Remove or loosen the #8 power terminal screws on the ONS 15454. To avoid confusion, label the cables
connected to the BAT1/RET1 power terminals as 1 and the cables connected to the BAT2/RET2 power
terminals as 2.
Note Use only pressure terminal connectors, such as ring and fork types, when terminating the
battery, battery return, and frame ground conductors.
Caution Before you make any crimp connections, coat all bare conductors (battery, battery return, and frame
ground) with an appropriate antioxidant compound. Bring all unplated connectors, braided strap, and
bus bars to a bright finish, then coat with an antioxidant before you connect them. You do not need
to prepare tinned, solder plated, or silver-plated connectors and other plated connection surfaces, but
always keep them clean and free of contaminants.
Caution When terminating power, return, and frame ground, do not use soldering lug, screwless (push-in)
connectors, quick-connect, or other friction-fit connectors.
Step 4 Strip 1/2 inch of insulation from all power cables that you will use. Crimp the lugs onto the ends of all
power leads.
