g. Measuring DC Voltage.

To measure dc volts (fig. 5-13), do the following steps:

(1)

Set up multimeter (see para f).

NOTE

If you are not sure of the voltage to be measured on the vehicle, always

start on the highest range shown in para f. This will protect the meter,

(2)

With any of the three multimeters, connect the red probe to the positive (+) side of

the circuit and the black probe to the negative (-) side. The example below shows 24 volts dc being

measured across the batteries.

Voltage

(3)

Read the meter. (Figures

5-14

thru 5-16 show how to read all three multi meters.)

If the needle tries to move off scale to the left, reverse the probes on the circuit.
