Cooling Systems QUESTIONS
Never attempt to "jump" or connect a battery charger to a (x) battery - Answer-frozen (it
will explode!)
any battery circuit with 801 CCA or more requires a ... - Answer-battery switch
Batteries shall not be installed directly (x) or (x) a fuel tank, fuel filter, or fitting in a fuel
line without an intervening sole, floor, or deck - Answer-above or below
battery cables and other conductors size 6 AWG and larger shall not be connected to
the battery with... - Answer-wing nuts
a maximum of (x) conductors will be placed on any one battery terminal - Answer-4
