TEST PROCEDURE 10 – Diode 1 on wire 32 and 35
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.
Disconnect the two-pin connector between the front gearcase and the wire harness.
3.
Set the multimeter to the diode test function.
4.
Connect the black (–) probe of the multimeter to the frame (ground).
5.
Connect the red (+) probe of the multimeter to the 18-gauge gray wire (w34) on the two-pin connector (wire
harness side).
6.
The reading should indicate an over limit (no continuity). If the diode conducts current (shows continuity, e.g.
beeps) with the meter probes connected as described, the diode has failed and must be replaced.
Harness Diode Removal on page 13-18.
7.
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.
8.
If the readings obtained in the previous steps are incorrect, replace the diode.
TEST PROCEDURE 11 – Diode 2 on wire 40 and 41
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.
Remove the start relay from the multi-pin connector located on the electrical component mounting plate.
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 18-gauge light-green wire (w110) at the start relay multi-pin
connector.
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.
