TESTING VOLTAGE DROP
NOTICE
If you disconnect the connector at the load, and
measure voltage with one lead on the power supply
wire, and one to ground, you will be measuring
available voltage. This is a static test and not dynamic
voltage drop testing. Refer to page Static and Dynamic
Testing page 10.30
The measurement of voltage is the DIFFERENCE in
electrical pressure between the two points your DMM
leads are touching.
Most circuits will have one load. The load is the
component in the circuit that uses the current flow to do
work, such as move a solenoid or light a bulb.
Voltage coming into the load should be near battery
voltage with current flowing. There will be some loss from
moving through electrical contacts in connectors and
relays, but it will be minimal.
NOTICE
You will need to backprobe to perform this test. For
information about doing this safely, refer to Connector
Probing Guidelines page 10.31
Voltage should be near fully depleted by the load. This
means that when measuring on the ground side of the
circuit, immediately after the load, back to battery
negative, you should have near zero pressure difference
(voltage).
If you do have a difference in pressure, this means there
is something adding resistance to the circuit such as
corrosion.
