This is a continuation of the Starting System Test, but can also be selected from the
VDrop Menu by selecting >MAG. CIRCUIT then press Enter. In the individual test you
will be asked to disconnect the Magnetic circuit from the “S” terminal on the starter
solenoid as explained on the previous page. This is necessary to avoid starting the
engine during this test sequence.
NOTE: ON 12 VOLT
SYSTEMS THE SMALL
BLACK LEAD CAN BE
LEFT DISCONNECTED OR
CAN BE CONNECTED TO
ANY GROUND. ON 24 VOLT
SYSTEMS THIS LEAD MUST
BE CONNECTED TO THE
STARTER GROUND.
Magnetic
Circuit 3-
Step Setup
The Magnetic switch circuit supplies a path for current to the coils of
the starter solenoid with minimum voltage drop. The Magnetic circuit is
indicated by the dotted line on the illustration below. The Magnetic circuit
test is designed to test the voltage drop of this circuit. It has three steps.
If it passes the first test the whole circuit passes and there is no need to
continue. If the first test fails, the next two tests are completed to obtain
results of each leg and the magnetic switch itself. The Magnetic switch
is energized by the ignition switch in each test.
For safety, disconnect the
negative cable from the battery while making the connections.

If the Amp Probe is attached you will be asked to zero it and attach it to the
starter cable. See page 19 for more information.
The starter draw test measures the amount of current needed to crank
the engine and provides the initial information to diagnose and/or further
test the starting system if necessary. What may appear to be a major
problem may turn out to be a minor problem. Also, what appears to be a
starter problem may be something more major.

Connect large leads to the starter.
Then connect small leads to the
battery.
Waiting for loading then start
or crank the engine when
instructed.
After a few seconds the test
result will appear.
