urrent drains, shorts and bad grounds are the
cause of many problems. The cause of the problem often seems to have nothing to
do with the symptom.
But, using a DMM, you can find the cause quickly without
burning a whole box of fuses. Current drains that run the battery dead are often
referred to as shorts, although they may not actually be short circuits. In
fact, they may be related to Keep Alive Memory or K.A.M.
Shorts that blow fuses
can be found using the same troubleshooting techniques used to find current
drains even though the symptoms are different.
CAUTION-Each vehicle manufacturer
has a different procedure for locating current drains. Using the wrong testing
method will give you erroneous results. To make sure you get the proper results,
please refer to the vehicle manufacturer’s procedure.
