Step 4
Remove or loosen the #8 power terminal screws on the ONS 15454. To avoid confusion, label the cables
connected to the BAT1/RET1 (A) power terminals as 1, and the cables connected to the BAT2/RET2 (B)
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 5
Strip 1/2 inch (12.7 mm) of insulation from all power cables that you will use.
Step 6
Crimp the lugs onto the ends of all power leads.
