BATTERY
Possible Cause Operation
Battery The battery is the electrical device in the system that requires
the most frequent inspections and thorough maintenance. If the
vehicle is not used for some time (1 month or more) the battery
needs to be recharged periodically. The battery runs down
completely in the course of 5 ÷ 6 months. If the battery is fitted
on a motorcycle, be careful not to invert the connections, keep-
ing in mind that the black ground wire is connected to the
negative terminal while the red wire is connected to the terminal
marked+. Follow the instructions in the ELECTRICAL SYSTEM
chapter for the recharging of the batteries.
