Connect  one  meter  test  lead  to  pin  location  J2-10 Wire  44S
of  the  connector  just  removed.  Be  careful  not  to  damage  the
pin  connectors  with  the  test  leads.  Connect  the  other  meter
test lead to Wire 44S at Terminal Block 2 (TB2). CONTINUITY
should be measured.
3. Connect one meter test lead to pin location J2-12 Wire 11S. Be
careful not to damage the pin connectors with the test leads.
Connect  the  other  meter  test  lead  to Wire  11S  at Terminal
Block 2 (TB2). CONTINUITY should be measured.

Figure 6-58. – Check Wires 11S & 44S
RESULTS:
1. If CONTINUITY was not measured, repair or replace the wire
harness.
2. If CONTINUITY was measured, refer back to the flow chart.
TEST 52 - CHECk IdLE CONTROL SWITCH 
(SW2)
PROCEDURE:
1. Set a voltmeter to measure resistance.
2. Disconnect Wire  0  and Wire  83  from  the  Idle  Control  Switch
(SW2).
3. Connect meter test leads across both  terminals of SW2. See
Figure 6-59.
4. In the OFF position the meter should read INFINITY or Open.
In  the  ON  position  the  meter  should  read  CONTINUITY  or
Closed.
RESULTS:
1. If the switch fails Step 4 replace it.
2. If the switch is good refer back to the flow chart.

TEST 53 - CHECk IdLE CONTROL WIRINg
PROCEDURE:
1. Set a voltmeter to measure resistance.
2. Disconnect Wire 0 from the Idle Control Switch (SW2).
3. Connect one meter test lead to Wire 0. Connect the other meter
test lead to frame ground. CONTINUITY should be measured.
If continuity is not measured repair or replace Wire 0 between
SW2 and the ground terminal.
4. Disconnect Wire  83  from  SW2.  Disconnect  the  J2  connector
from the printed circuit board.
5. Connect  one  meter  test  lead  to Wire  83  previously  removed
from  SW2.  Connect  the  other  meter  test  lead  to  pin  location
J2-2  on  the  J2  connector.  See  Figure  6-60.  Be  careful  not  to
damage the pin connectors with the test leads. CONTINUITY
should be measured. If CONTINUITY is not measured repair or
replace Wire 83 between the J2 connector and Terminal Block
or between the Terminal Block and SW2.
