(cont'dl
6. Check the following items in the order listed untilyou find the open circuit.
. Check the BLIVWHT wire and connectors
between the under-dash fuse/relay box and theignition switch, and between the under-dash
fuse/relay box and the starter.. Check the ignition switch {see page 22-53).. Check the clutch interlock switch and connector.. Check the starter cut relay (see page 22-51).. Check LT GRN wire between the starter cut relayl
under-dash fuse/relay box and the clutch
interlock switch.. Check the BLK wire between the clutch interlock
switch and G501.
7, Check the cranking voltage and current draw.
ls ctanking voltage greatet than or equal to 8.7 V
and current draw less than or equal to 230 A?
YES-Go to step 8.
NO Replace the starter. or remove and
disassemble it, and check these items until you find
the cause.
. Starter armature dragging. Shorted armatu re winding. Excessive drag in engine
8. Check the engine speed while cranking the engine.
ls the engine speed above 100 tpm?
YES Go to step 9.
NO-Replace the starter, or remove and
disassemble it, and check for the following untilyou find the cause.
. Excessively worn starter brushes. Open circuit in commutator brushes. Open circuit in starter armature commutator
segments. Dirty or damaged helical splines or drive gear. Faulty drive gear clutch

against the diaphragm spring. which can result in
clutch slippage or other clutch problems.
1. Loosen the clutch pedal position switch locknut (A),
and back off the clutch pedal position switch (B)
until it no longer touches the clutch pedal (C).

4. With the clutch pedal released. turn the clutchpedal position switch (B) in until it contacts the
clutch pedal (C).
5. Turn the clutch pedal position switch {B) in an
additional 3/4 to 1 turn.
6. Tighten the clutch pedal position switch locknut (A).
7. Loosen locknut (J)and the clutch interlock switch(K).
8. Press the clutch pedal to the floor.
9. Release the clutch pedal 10 'l6mm(0,39 0.63in.)
from the fully pressed position, and hold it there.
Adjust the position of the clutch interlock switch (K)
so that the engine will start with the clutch pedal in
thls position.
