STARTER NEG. CABLE VOLTAGE DROP
STEWE-R TEST 69
1. Start Test 69. Starter Negative Cable
Voltage Drop.
2. Displayed reading is in volts. The cable
voltage drop should be less than 0.25 volt
max.
DC VOLTAGE O-46 VOLTS
STEIlCE-R TEST 69
1. Connect RED clip to the indicated test point,
BLACK clip to negative or ground.
2. Start Test 69. DC Volts.
3. Displayed reading is in volts.
BAlTERY CURRENT
MULTIMETER
1. Set the voftmeter to a DC volts scale of about
1 volt.
2. Connect the BLACK lead to the battery side of
the current shunt and the RED lead to the
other end of the current shunt.
3. Current shunt voltage is proportional to
battery current, 100 millivolts = 1.000 amps.
To get current, multiply miliiolts x 10.
VOLTAGE
MULTIMETER
1. Set the voltmeter to a DC volts scale of at
least 40 volts.
2. Connect the RED lead to positive and the
BLACK lead to negative.
3. Be sure to read the correct scale.
