ACTUATOR TEST

	TheActuatorTest is used to check the operation of many of he computer-con-
	trolled relays and solenoids. This is also helpful for checking voltages and output
	signals. Use a voltmeter to check the output signals at each relay and solenoid
	to verify their operation. To do this, take voltage readings at relays and solenoids
	before beginning this test. Then activate the					t o energize the relays and sole-
	noids. Check voltages again to determine if they are functioning properly.
	Remember to write down readings for refer nce.
