2.
Raise the hood and disconnect the multi-pin connector from the key switch.
3.
Disconnect the bullet connector in the carburetor solenoid green wire
.
4.
Set the multimeter to the diode test function.
5.
Connect the black (–) probe of the multimeter to the frame (ground).
6.
Connect the red (+) probe of the multimeter to the female side of the carburetor solenoid bullet connector.
7.
The reading should indicate an over limit (no continuity). If the diode conducts current (shows continuity) with
the meter probes connected as described, the diode has failed and must be replaced.
8.
Reverse the multimeter probes and note the reading. The multimeter should indicate approximately 540 mV,
however, a range of 400 to 700 mV is acceptable.
9.
If the readings obtained in the previous steps are incorrect, replace the diode.
TEST PROCEDURE 14 – Diode 5 on wire 131 and 129
See General Warnings, Section 1, Page 1-2.
1.
Disconnect battery and spark plug wire(s).
See Side-Post Battery: Disconnecting the Battery –
Gasoline/Diesel Vehicles on page 1-3.
See Top-Post Battery: Disconnecting the Battery- Gasoline/Diesel Vehicles on page 1-4.
2.
Raise the hood and disconnect the multi-pin connector from the key switch.
3.
Disconnect the six wire engine harness connector located near the starter
.
4.
Disconnect the 16-gauge green wire (w127) from the starter solenoid coil
.
5.
Set the multimeter to the diode test function.
6.
Connect the black (–) probe of the multimeter to the frame (ground).
7.
Connect the red (+) probe of the multimeter to the 16-gauge green wire (w127) at the spade connector.
8.
The reading should indicate an over limit (no continuity). If the diode conducts current (shows continuity) with
the meter probes connected as described, the diode has failed and must be replaced.
9.
Reverse the multimeter probes and note the reading. The multimeter should indicate approximately 540 mV,
however, a range of 400 to 700 mV is acceptable.
10.
If the readings obtained in the previous steps are incorrect, replace the diode.
