If the battery needs to be removed from the vehicle before
charging, always remove the grounded terminal from the battery
first, also ensure that all accessories in the vehicle are tuned off to
prevent arcing.
Ensure the battery terminals are clean.
Always refer to the manufacturer’s instructions regarding charging
and charging rates and battery maintenance.
OPERATION
1. CONNECTION
If Battery is Installed in a Vehicle
Check polarity of battery terminals – for top mounted battery
terminals, the Positive post (marked POS, P, +) usually has a
larger diameter than the Negative battery post (marked NEG, N,-).
For side mounted battery connections, the terminals are marked
Positive (RED) and Negative (BLACK).
Attach charger clamps to the battery terminals, ensuring a secure
connection. If charger clamps are not secure or connected
incorrectly, the Reverse Polarity Indicator on the front panel will
illuminate.
Negative-Grounded Vehicle: Connect the Positive (RED) charger
clamp to the Positive (POS, P, +) ungrounded battery terminal.
Then, connect the Negative (BLACK) charger clamp to the vehicle
chassis, or the engine block (away from the battery). Do not
connect the clamp to the carburetor, fuel lines, or sheet-metal
body parts Connect only to a heavy gauge metal part of the frame
or engine block. NOTE: Negative- Grounded type systems are the
most common in today’s vehicles.
