• Give insight into the reasons for performing a procedure in the recommended manner, and / or
Present information that gives the technician the benefit of past experience in accomplishing a procedure with greater
ease.
1.2 Battery Terminals and Cables
The cables attached to the battery posts provide power and ground connections for the vehicle electrical system. These
battery cables attach to the battery posts via nut-tightened terminals. The battery is held in position by a hold-down
bracket and bolts. Refer to Figure 6D1-3 – 1.

1.3 Battery Ratings
There are two battery ratings to consider when replacing a battery, reserve capacity (RC) and cold cranking amps (CCA).
Ensure the replacement battery meets or exceeds these rating specifications.
Reserve Capacity
The RC of a battery is the amount of time (measured in minutes) the vehicle will travel at night with minimum electrical
load and no generator input.
