Section 10. Electrical System
10-12 Model 6036 S/N 9B0499 and Before
solenoid terminal and the starter yoke.
Operate the starter.
2. If no volts are indicated, check for:
• poor lug connections at battery
• bad ground connection
• broken starter lead, batteries to starter
3. If full voltage (12 to 14 V) is indicated, check
for:
• Faulty solenoid switch
• Open circuit in starter (check brushes)
4. Reconnect the wire from the fuel shut off
solenoid at the fuel injection pump.
b. Test 1—Voltage Loss in Complete Starting
Circuit
1. Disconnect the wire from the fuel run solenoid
(2, Fig. 10.42) at fuel injection pump, Fig. 10.9.
2. Turn ignition key to the ON position.
3. Connect a remote starter button to the battery
and ignition switch terminals on the starter
solenoid.
4. Select voltage range that will measure 12 Vdc.
5. Move the voltage lead switch on the voltmeter
to the EXT position.
6. Connect the positive lead of the voltmeter to
the positive battery cable at the battery.
7. Connect the negative lead of the voltmeter to
the negative battery cable at the battery.
8. Push in and hold the starter button and read
the voltmeter.
a. If the voltmeter indicated 9.6 V or more,
the starting circuit is in good condition and
no other testing is required.
b. If the voltmeter indication was less than
9.6 V, complete Test 2.

10.5.2 How to Check Voltage Loss
in the Starting Circuit
• The starter remains on the engine for
these tests.
• Do not operate the starter for more than
15 seconds at one time. After the starter
has run for 15 seconds, let the starter cool
for two minutes before operating the
starter again.
• These tests will require a voltmeter.
a. Voltage Specifications
Minimum voltage while starter is running 9.6 V
Maximum voltage loss:
• Positive battery cable and starter solenoid
0.5 V
• Each cable
0.4 V
• Starter solenoid
0.1 V
• Each connection
0.0 V

c. Test 2—Voltage Loss in the Positive
Battery Cable and Starter Solenoid
1. The positive lead of the voltmeter stays
connected to positive battery cable, Fig. 10.10.
2. Connect the negative lead of the voltmeter to
the starter motor terminal on the starter
solenoid.
3. Push in and hold the starter button and select
the lowest range for the voltmeter. Read the
voltmeter.
