Connecting To The Battery

Do not connect the AC power plug until all other connections are made. Identify the correct polarity of the battery terminals on the battery. The positive battery terminal is typically marked by these letters or symbol (POS,P,+). The negative battery terminal is typically marked by these letters or symbol (NEG,N,-). Do not make any connections to the carburetor, fuel lines, or thin, sheet metal parts. The below instructions are for a negative ground system (most common). If your vehicle is a positive ground system (very uncommon), follow the below instructions in reverse order.

1.) Connect the positive (red) battery clamp or eyelet terminal connector to the positive (POS,P,+) battery terminal. 

2.) Connect the negative (black) battery clamp or eyelet terminal connector to the negative (NEG,N,-) battery terminal or vehicle chassis. 

3.) Connect the battery charger’s AC power plug into a suitable electrical outlet. Do not face the battery when making this connection.

4.) When disconnecting the battery charger, disconnect in the reverse sequence, removing the negative first (or positive first for positive ground systems).

The steps are illustrated below for clamps and eyelets (for negative ground systems). 

                                                                   Clamps                                                                                                                                            Eyelets                                   

Connecting the clamps to the battery.

1.) Although the clamps can be put on in any order, we strongly suggest to start with the positive clamp for negative ground systems (most common). The circuit will not be complete until the negative clamp is attached, reducing margin for error or injury.

2.) Attach the negative clamp to the battery. 

*Remove in opposite order. Negative first to break the connection, then positive.

Connecting the eyelets to the battery.

1.) Although the eyelts can be put on in any order, we strongly suggest to start with the positive eyelet for negative ground systems (most common). The circuit will not be complete until the negative eyelet is attached, reducing margin for error or injury.

2.) Attach the negative eyelet to the battery. 

*The eyelets can safely be left on the battery for quick connection in the future, but if the need arises for them to be removed, remove in opposite order. Negative first to break the connection, then positive.

Follow the same guidelines when using other approved NOCO accessories to connect to a battery or vehicle application.
