4. Indicator Lamp Circuit -

Connect two 1.5 v dry cell batteries in series. Using the table, check that each suspect Indicator Lamp illuminates.

NOTE:
Since the Indicator Lamps are LEDs, do not mix the "+" and "-" terminals of the test batteries or apply power to them for more than 3 seconds at a time.

If a suspect LED does not illuminate when tested, replace the Control Switch.
