Uh, not quite Jack......... Yes, the intermittent = relay failed (melted parts) because it was held in too long, but in the = odd Lancair terminology environment:
 
S =3D = Switch (+12VDC, while the other side of the coil is grounded through the = case) coming from the pressure switch and thence from the gear selection = switch through the 5 A breaker/fuse that folks forget to pull when they = pull the pump breaker whilst power is supplied from the main bus and the = particular pressure is low enough to allow the pressure switch to = make.
 
I =3D Indicate =3D +12 VDC available as = a tap off of the contactor plate when it makes the connection betwixt = power and pump used to provide  the positive voltage to the lamp on = the console marked "pump in transition".
