GLOW PLUGS CIRCUIT
DC VOLTAGE O-45 VOLTS
STEdCE-R TEST 89
1. Connect RED dip to the indicated test point,
BLACK clip to negative or ground.
2. Start Test 89, DC Volts.
-3. Displayed reading is in volts.
VOLTAGE
MULTIMETER
1. Bet 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.
RESISTANCE AND CONTINUITY
04,500 OHMS
STEnCE-R TEST 91
1. Connect RED dip and BLACK clip to the
indicated test points in the question.
RED to
the first, BLACK to the second.
2. Start Test 91,0-4.500
Ohms.
3. Displayed reading is in ohms. Less than 5 ohms
is continuity.
If the resistance is over 4.800
ohms, STEXE-R
displays .9.9.9.9.
CONTlNUllY
(RESISTANCE)
MULTIMETER
1. Set the voltmeter to an ohms scale of about
1.000 ohms.
2. Connect the RED and BLACK leads to the
connections stated in the question.
3. Be sure to read the correct scale. Less than
5 ohms indicates continuity.
For an open
circuit, the meter should peg full scale
(needle all the way to the left).
