•  Should  utility  voltage  drop  below  approximately  65  percent  of  the  nominal  source  voltage,  a  programmable

timer on the circuit board will turn on.

•  In Figure 2, the 10-second timer is still timing and engine cranking has not yet begun.
•  The AUTO-OFF-MANUAL switch is shown in its AUTO position. Battery voltage is available to the circuit board

via Wire 13, a 7.5 amp fuse (F1), and Wire 15B.
