Electrical Components
Let’s look at components and the testing of the components.

Battery
A battery is an electrochemical device that can store
electrical energy.
Caution: Gas vapor from a battery is flammable.
Keep all sparks and flames away from a battery or an
explosion can occur.
There are two basic battery tests
Battery
Specific Gravity Test (use table)
The specific gravity or weight of the battery
electrolyte indicates state of the battery charge. A
battery hydrometer measures the specific gravity of
the electrolyte. Hydrometers are calibrated to
measure specific gravity correctly at an electrolyte
temperature of 80ºF. To determine the correct
specific gravity reading when the temperature of the
electrolyte is other than 80ºF: Add to the hydrometer
reading four gravity points (0.004) for each 10ºF
above 80ºF. Subtract four gravity points (0.004) for
each 10ºF below 80ºF.
Amperage load should equal one-half the cold
cranking amperage of the battery
