Connecting to the battery
1) Identify polarity of battery posts. 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, –).
2) Do not make any connections to the carburetor, fuel lines, or thin metal parts.
3) Identify if you have a negative or positive grounded vehicle. This can be done by identifying which battery post (NEG or POS) is connected to the chassis.
4) For a negative grounded vehicle (most common): connect the RED POSITIVE clamp first to the positive battery terminal, then connect the BLACK NEGATIVE
clamp to the negative battery terminal or vehicle chassis.
5) For a positive grounded vehicle (very uncommon): connect the BLACK NEGATIVE clamp first to the negative battery terminal, then connect the RED POSITIVE
clamp to the positive battery terminal or vehicle chassis.
6) When disconnecting, disconnect in the reverse sequence, removing the negative first (or positive first for positive ground systems).
7) A marine (boat) battery must be removed and charged on shore. To charge it on board requires equipment specially designed for marine use.
