Curien Round Terminal Pin Kit
and Back Probe Lead Set
Reviewed by Jaime Lazarus, retired technician from Ocala, Fla.
T
he Back Probe Lead Set
saves time because it's
one component - an alligator
clip lead. It's not two (or
more) separate components
that, when assembled, become
an alligator clip lead. When compared
to the latter, readings are
more accurate too.
The Round Pin Terminal Set (RPTS)
saves time when it's necessary to probe
connectors or components carefully and
accurately. These can replace several test
leads, which can deliver unreliable meter
readings over time.
The RPTS is probably the last set of
round test terminals you'll buy. It took
a few moments to figure out how to use
the components, but no time at all to use
the lead.
The RPTS came boxed with little packaging
waste, has identifiable spaces for all
components, and fits neatly in a toolbox.

PRODUCT DESCRIPTION
The Curien Round Pin Terminal Connector Set is ideal for connecting directly
to sensors, ECM's, or other connectors to slide directly into the circuit connector
without attempting to back probe the wiring and/or damage the terminal fit of the
connector or seals after users are done. The male and female sizes are: 1.5mm,
2.0mm, 2.5mm, 3.5mm, and 4.0mm. The set also includes a female spade slot
adapter to fit male spade connectors and a 3 " flexible extender to allow users to
connect to pins in deep connectors.
The Curien Back Probe Lead Set, No. BPLS101, is ideal for back probing and
getting readings on sensors, connectors, and other sensitive and hard-to-reach
areas. The set includes a 10' green 18-gauge copper lead with alligator clip and gold
plated 4mm banana jack and six 2 " steel T-pins. The 10' cable allows for Curien's
N2 to be placed strategically for optimal safety while going for test rides or other
functional testing. Made in the U.S.A.

longer than most leads, so a technician
has more mobility when testing electrical
circuits. The RPTS is gold-plated solid
brass, so they're sturdy, very electrically
conductive, and non-tarnishing (which
can affect the meter readings).
The BPLS could be improved by
crimping the alligator clip to the wire
insulation, thereby relieving any strain
on the wire conductor (and extending the
life of the lead).
The RPTS could be improved with the
inclusion of more " spade " type terminal
test components of various sizes. The one
that is included is too large for many of
today's applications. I'd also suggest insulating
the outsides of the female terminals.
I used the RPTS to perform conductivity
tests on a wiring harness while using
the BPLS as one of my meter leads during
the test.
The RPTS I'd rate at an eight and the
BPLS a nine. Both products are above
average quality, but both have some room
for improvement.
