11..22 TTeessttiinngg IInnssttrruummeennttss
You may use two test instruments to check the electrical components:
11.. A voltmeter
22.. An ohmmeter
NOTE: When the manual refers to the circuit being closed, the ohmmeter should read
zero unless otherwise noted. When the manual refers to the circuit being open, the
ohmmeter will read infinite resistance.
11..33 TTrroouubblleesshhoooottiinngg
