Then connect small leads to the
battery or along the circuit being
tested as illustrated in the setup
and press (Y Enter).
If all connections are correct, wait
for a load to be applied.
The results will vary depending
upon and the conditions of the
cables. Both the positive and
negative circuit results will be
indicated from the single test.
If the overall voltage drop is not within the desired specifications the
small leads can be moved closer along the line being tested and the test
run again (see dotted lead on previous page). If the results are desirable,
it is the section not included in the last test. If the results are not
desirable the problem is most likely in the section being tested. Repair
and test the entire section again.
