CAUTION: Remove power from both
the BAT1 and terminal blocks
prior to servicing
Use only pressure terminal connectors, such as ring and fork types, when terminating the battery,
battery return, and frame ground conductors.
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.
When terminating power, return, and frame ground, do not use soldering lug, screwless
(push-in) connectors, quick-connect, or other friction-fit connectors.
