DIODE LOCATION
(WIRES)
Diode 1 w32 and w35
Diode 2 w40 and w41
Diode 3 w45 and w39
Diode 4 w130 and w122
Diode 5 w131 and w129
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 Disconnecting the Battery – Gasoline/Diesel Vehicles on
page 1-3.
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. See Wire
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.
FUNCTION
Front differential coil flyback diode
(only used in AWD applications but
still present in 2-wheel drive vehicle
harness)
Blocking diode for carburetor solenoid
control (powers carburetor solenoid
when key switch is in the START
position)
Carburetor solenoid control (powers
carburetor solenoid when key switch is
in the ON position)
Carburetor solenoid coil flyback diode
Starter solenoid coil flyback diode

Test Procedures
FAILURE
SYMPTOM/COMMENT
CONDITION
Will contribute to the premature failure
Open of the limit switch (switch is only used
in AWD vehicle).
The 10-amp fuse (on w109) will blow
repeatedly, with the key ON & pedal
Closed
depressed, until the diode has been
replaced.
Open Difficult starting or not start at all
Starter will be activated when key
Closed
switch is in the ON position.
Difficult starting and engine will shut off
Open shortly after key switch is moved from
the START to ON position.
Oil light may illuminate when key is in
START position until oil pressure rises.
Closed
Hour meter will be powered when key
switch is in the START position.
Will contribute to the premature failure
Open
of the key switch contacts.
The 10-amp fuse (on w109) will blow
Closed repeatedly, when key is in ON position,
until the diode has been replaced.
Will contribute to the premature failure
Open
of the start relay contacts.
The 25-amp fuse (on w125) will blow
repeatedly, when key is in START
Closed
position, until the diode has been
replaced.
