ELECTRICAL

CONNECTOR PROBING GUIDELINES

FRONT PROBING
Front probing is accomplished by pulling the harness
connector from the component, and then taking a
measurement from the terminal face. This is the
measurement taken in most situations.
The terminals in electrical connectors are small and
fragile. Do not probe directly with your meter leads, as
the meter leads are larger than almost all terminals.
Probing with a meter lead will likely damage the terminal
by spreading it beyond it’s design limits, causing no BACK PROBING
tension. If there is no tension, you will have either no Back probing is typically not advisable on sealed
connection or a poor connection. connectors, as it can easily cause damage to the wire,
terminal, connector body, or body to wire seal.
To avoid causing damage, use of the appropriate
adapters is required. Most terminals used on Polaris NOTE
machines can be tested using terminal test kit PV–
43526. It includes male and female adapters that can be There are commercially available back probe kits. Fine,

also work well for back probing.

If back probing must be done to see voltage drop while
current is flowing in the circuit (dynamic testing), ensure
it is done only on connectors that are large enough to
accommodate the probe. Ensure back probing is done
gently and carefully. Ensure no damage has been done
after probing.

PV– 43526 adapters are also used as known good
terminal drag testers. Insert the male tester terminal into
the female connector on the harness. There should be a
noticeable amount of force to install and remove the
tester, and you should be able to tip the harness
connector with the tester hanging from the connector,
and not have the tester fall out.
