I have a Massimo MSA550 ATV bought new last year. Last fall I removed the battery to trickle charge for the winter months. The battery is located under the seat. QUESTION... When preparing to reinstall the battery this spring, I find (2) positive (red) cables and (2) ground (black) cables loose in the battery location. I only recall disconnecting (1) cable from each battery post. Can anyone tell me if both cables (red) and both (black) cables connect to the battery, or just one set? The manuel does not show the answer.
