One of the most widely used tools used for testing a 12 Volt problem is
the test light. Many different types of test lights are available, such as a light
bulb with a probe and ground clip, to the more elaborate electronic ones that
measure a wide scale of voltages and perform a variety of functions. A VOM
or Volt Ohm Meter is used to perform a multitude of tests. It is generally
used when exact values are needed for evaluation. These meters come in an
analog or digital format. Either of these two testing tools may be used,
depending upon personal preference. If a 12 Volt light is not working, the test
light may be better suited for this. In the event of a charging system problem,
where exact voltage values need to be obtained, the meter may be the tool of
choice. In any situation the testing tool is an invaluable piece of equipment
when it comes to determining an electrical problem.
Should it become necessary to use testing tools, take certain precautions
and consider three things. First, recognize when the problem is beyond your
skill level. Nothing will create more mayhem than being armed with tools
and going in an unknown direction. Good intentions may lead to major prob-
lems. The second item to keep in mind is if something will cause more grief
by being dealt with now, than if it were left alone and repaired by a profes-
sional at a more convenient time. How many times have you said to yourself,
“Oh this will only take a few minutes,” only to find it is taking an entire day
and you wished you had not touched it. The third item to consider is whether
or not the current situation may become potentially dangerous if left to be
repaired at a more convenient time?
NOTE: Check all related fuses before assuming you have
encountered an electrical problem or situation. Spare fuses
should be kept on hand, and can be purchased from auto
parts stores. A fuse description label is on the distribution
panel cover.
WARNING: If a fuse blows, replace the fuse with same
amperage rating and type. Installing higher amperage
fuses can damage the wiring or the item the fuse is protect-
ing, or may cause a fire. If the fuse repeatedly blows after
replacing it, do not continue to replace it. Have the prob-
lem diagnosed and corrected by a qualified technician.
Batteries come in different sizes, types, amp hours, voltages and
chemistries. There are nearly as many descriptions of battery types and how
they should be used, as there are people willing to offer advice on them.
Although it is not
possible to cover batteries in their entirety, there are guidelines that can be
followed to ensure that the batteries are well maintained.
The operation of the battery is based on a chemical reaction. The battery
is a container of lead plates, insulators and a solution of distilled water and
