TEST 54 - CHECk IdLE CONTROL 
TRANSFORMERS (ICT)
PROCEDURE:
1. Set a voltmeter to measure resistance.
2. Remove  the  two  Idle  Control Transformer  (ICT) Wires  from
Terminal Block 1 (TB1). See Figure 6-61.
3. Connect one meter test lead to one wire and connect the other
meter  test  lead  to  the  other  wire.  Approximately  100  ohms
should  be  measured.  If  resistance  is  not  measured  repair  or
replace the Idle Control Transformers. If resistance was mea-
sured proceed with Step 4.
4. Set a voltmeter to measure AC Voltage.
5. Connect one meter test lead to one wire and connect the other
meter test lead to the other wire.
6. Turn  the  Idle  Control  Switch  (SW2)  to  OFF. The  generator
should be running at about 60 HZ.
7. Apply a light load to the generator, such as a electric drill.
8. When the drill is activated measure the voltage output. The AC
voltage should measure around 1-2 VAC.
RESULTS:
Refer back to flow chart.
