Use extreme care when checking live voltage. Do not touch live 
terminals, wires, or ground. Failure to use caution could result in 
serious electrical shock injury.

b. At P1, measure the voltage between common (pin 1) and 32V (pin 3) 

(see figure 3-4 on page 3-5).

c. The voltage is 32V AC +3V.

Yes

No

↓

Go to step 10.

8. Perform the following:

a. Set your VOM to read volts AC.

SHOCK HAZARD:

Use extreme care when checking live voltage. Do not touch live 
terminals, wires, or ground. Failure to use caution could result in 
serious electrical shock injury.

b. At P1, measure the voltage between common (pin 1) and 12V (pin 2) 

(see figure 3-4 on page 3-5).

c. The voltage is 12V AC +3V.

Yes

No

↓
