(3) Simpson 160, Refer to figure 4-7.
(2) Disconnect the battey ground cable at the
battery. Then disconnect the circuit you are going to test.
(a) Set the selector switch to RX1.
(3) Connect the meter probes to both terminals
(b) Put the black probe in the COM-jack.
of the circuit you are testing (fig. 4-8).
(c) Put the red probe in the + jack.
(4) Read the meter. Interpret the results as
follows:
(d) Now zero the meter by touching the
probes together and turning the ADJ knob until the
needle is over the (1 on the top scale.
(a) If the needle swings over the 0 on the top
scale, the circuit has continuity.
b.
check for breaks in a circuit (such as a switch, light bulb, or

open. The wire is broken and must be replaced.
(1) Zero the meter (para 4-10).
(c) If the needle jumps or flickers, there is a
loose connection somewhere in the circuit being tested.
CAUTION
Make sure the meter leads are pressed firmly against the
test points, If the meter lead connections are firm, tighten
