Turn one of the cooktop burner valves to
the LITE position.

4.

Touch the test leads to the J1 connector at
terminals  4  (white)  and  9  (red).  The  AC
voltmeter should indicate 120 VAC. If not,
check  the  ignition  switch  and  the  main
wiring harness.

3.

Touch the test leads to the J1 connector at
terminals 4 (white) and 10 (black). The AC
voltmeter should indicate 120 VAC. If not,
check for the proper voltage at the power
supply outlet, and check the main wiring
harness.
