......2.5 & 10 , on our Hot-airs . I copied this from Vortex awhile Back :
"There are actually two lights that come on under boost.
They work as follows;
light When the boost rises above 2.5 inches of mercury the first setpoint in the round hobbs type switch is reached, it shorts the wht/blk stripe wire to ground to light the first light, when 10 inches is reached the second switch inside shorts the light blue/yellow stripe wire to ground lighting the second."
As far as ' Cut out ', I have'nt a clue ?
