Figure 4-11. TS-352B/U continuity test.
(d) Look at the meter needle.
1. If the needle swings to the far right
over the o on the top scale (on all three multi-
meters), the circuit has continuity.
2. If the needle doesnt move, the circuit
is open (broken).
3. If the needle jumps or flickers there is
a loose connection in the circuit being tested.
(3) Testing for Shorts. A short (or short cir-
cuit) occurs when two circuits that should not be
connected have metal to metal contact with each
other. A short also occurs when a circuit that should
not touch ground has metal to metal contact with
ground. To check for shorts, do the following steps:
(a) Set up and zero the multimeter (fig.
Failure to do the following step can
damage the multimeter.
(b) Disconnect the circuit being tested. To
be safe, disconnect the battery ground strap.
(c) With all three multimeters, connect one
probe to one circuit and the other probe to the other
circuit or ground (if checking for a short to ground).
The example below (fig. 4-12) shows a check to see if
wire A is shorted to wire B in the wiring
