The engine temperature must be below 90° F (32°C)
to get voltage here. If the engine is warm,
either wait for it to cool, or go to step C3 at the
bottom of the pegs and remember that the
cold advance maybe the problem if everything
else checks out OK.
The Glowplugs or the lntake/Exhaust
System may be faulty, so you should test
The cold advance circuit advances the fuel injection
pump timing approximately 3 to 5 degrees during
cold start up. If engine temperature is less than
90°F (32°C), then Advance circuit operation maybe
checked as follows:
Start the engine.
Disconnect wire 569B/569D from the
Advance Solenoid. If the circuit is working
correctly, then engine RPM should decrease.
Look at the advance mechanism on the
right side of the fuel injection pump
while you connect and disconnect 569D/
569B with the engine running. The
advance mechanism should move about
If the advance mechanism is stuck, apply
some oil at the points shown and try again.
Remember to reconnect any wires
that were disconnected during
0-45 DC VOLTS
STE/ICE-R TEST 89
1. Connect RED clip to positive, BLACK clip to
negative or ground.
2. Start Test 89, DC volts.
3. Displayed reading is in volts.
1. Set the voltmeter to a DC volts scale of at least
2. Connect the RED lead to positive and the
BLACK lead to negative.
3. Be sure to read the correct scale.
