cable to good metal engine ground away from the battery. Ensure you do not connect the black cable to fuel lines or
sheet-metal body parts.
4. Charging a positively grounded battery. Connect the black cable to the negative terminal on the battery and the red
cable to good metal engine ground away from the battery. Ensure you do not connect the red cable to fuel lines or
sheet-metal body parts.
Connecting the charger to an out of vehicle battery:
1. The power cord should be disconnected when connecting or disconnecting the battery leads.
2. Connect the red cable to the positive terminal on the battery and the black cable to the negative terminal.
3. If the battery leads have been connected incorrectly, the reverse polarity protection system will ensure that neither the
charger nor the battery are damaged.
