Power Supply Cut Delay
When the starter switch is on, the signal from the starter
switch ACC enters the right switch panel, passes
through the timer, operates the transistor on the battery
relay line on the right switch panel from the CN13
terminal 2 to the battery relay. The output is 0.5 seconds
after turning on the starter switch. The out is from the Br
terminal of the starter switch to the battery relay.
When the starter switch is OFF, after seven seconds, the
transistor is OFF and the output to the battery relay is
cut so that the battery relay is OFF.
When turning on the starter switch within seven seconds
after turning it OFF, the output to the battery is still on.
