Continuity tests are made to check for open
c i r c u i t s (breaks or disconnections) in leads,
harnesses, connectors, and switches. Follow the
instructions below to make a continuity check.
T h e TS-352 B/U multimeter is
s h o w n in these instructions, but
the procedures are similar for any
of the multimeters.
Set and zero rnultimeter for OHMS RX1.
The multimeter can be
damaged unless power is
r e m o v e d from the circuit being
Disconnect circuit being tested from its power
source. To be safe, disconnect the negative
battery cables (page 2-24).
Connect multimeter probes to both terminals
of circuit being tested. (See illustration.)
All electrical circuits have a small
amount of resistance. When
testing a long cable, the needle
may not quite reach the 0 point,
even when the circuit is good.
Watch the multimeter needle for the following
· If needle swings to 0 on OHMS
scale, the circuit has continuity.
· If needle stays at infinity
· If needle jumps or flickers, there is a
loose connection in the circuit being
