Step 23. RESISTOR R3 TEST
Set DMM to
DMM probes
measure resistance. Connect
to TP23(+) and J1-A(-).
DMM reading is 2700 to 3300 ohms.
If not, replace lamp test CCA. If still bad, go to
troubleshooting schematic 26.
Step 24. RESISTOR R9 TEST
Connect DMM probes to J7-C(+) and
TP24(-).
Step 25. RESISTOR R4 TEST
a. Set test adapter switch S1 to 1.
b. Connect DMM probes to J1-T(+) and
TP24(-).
Step 26. RESISTOR R6 TEST
a. Set test adapter switch S1 to OFF.
a. No response,
b. Connect DMM probes to J1-B(+) and
b. DMM reading is 900 to 1100 ohms.
TP24(-) .
If not, replace lamp test CCA. If still bad, go to
troubleshooting schematic 26.
DMM reading is 1600 to 2000 ohms.
If not, go to chart 29.
a. No response.
b. DMM reading is 900 to 1100 ohms.
If not, replace lamp test CCA. If still bad, go to
troubleshooting schematic 26.
