OHM TESTING AND POWER FEED
To test, first disconnect the device or load being operated from the circuit,
then contact the probe tip to the circuit being tested. Disconnecting the
component from the circuits prevents it from affecting and altering the
resistance reading.
Ohmmeter can also be used on wires or components not connected to
battery power or ground. Simply connect the item being tested between
the probe tip and the auxiliary ground lead and read the resistance read-
ing in Ohms.
While it is possible to ohm check some components, it should be noted
that Ohmmeter and PFT are primarily for use on wiring only and should
never be connected to a solid state component such as a module.
In Feed Test, you will see the LED’s light if the circuit is within the LED limits
and if they do not, you can see the actual voltage drop on the display.
