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.
2. Set your VOM to measure V DC. At P1, measure the voltage between pin 1
and pin 3 (see figure 3-4 on page 3-5, and figure 3-6 on page 3-6). Activate
the head up switch. The voltage is 12V DC (+ 3V).

between VCC (common) (pin 8) and VSS (pin 9) (see figure 3-4 on page
3-5, and figure 3-6 on page 3-6). Activate the head up switch. The voltage
is 28V DC (+ 4V).
