The ACC line for the starter system is connected
commonly on the positive end of each lamp. The
negative end is controlled by the transistor on the right
switch panel, when the transistor is earthed the lamp is
illuminated.
There is also a transistor before the diode on the
negative side of each lamp. When the lamp check
button, on the right hand switch panel is pressed, each
transistor is energised and the negative ends of all the
lamps are earthed, illuminating all the lamps to enable a
check.
