Knowing When to
Say When

One of the most widely used tools for testing a 12 Volt problem is the test
light. Test lights come in a host of varieties, 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 case of a charging system problem 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 have led to major problems.
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 professional 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 be 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 protecting, or may cause a fire. If the
fuse repeatedly blows after replacing it do not continue to replace it.
Have the problem diagnosed and corrected by a qualified technician.
