Abstract:
A leak detector functional assurance apparatus with a warning indication circuit to detect a liquid coolant radiator leak in a vehicle engine hood area, comprising: a liquid leak detector container installed in series with an overflow hose on said radiator leading to an overflow tank, further comprising a plastic foam float formed of proper size to fit within said container and having a magnet inserted therein, said float having round head brass brads in each corner thereof to provide positive rise and fall of the float within the coolant container, and a switch actuator assembly having electrical contacts for said warning circuit formed by a top brass strip holding a magnet and a bottom brass strip both secured to front wall of said container, where the top brass strip is positioned horizontally to enable making electrical contact with the float magnet when the top strip is drawn towards said container wall by said float magnet so that the two magnets will never fail to close the electrical contacts of said switch actuator because the spring tension of the brass strips within said assembly plus the points of contact being in a horizontal position serves to prevent any electrical contact due to any occurrence of mechanical vibrations.
