Grounded wiper assembly for fuel sensor
View Patent ↗A grounded wiper assembly for a fuel sensor includes a wiper housing for rotation relative to a variable resistor and a wiper with at least one contact operatively supported by the wiper housing for contacting the variable resistor as the wiper housing rotates. The grounded wiper assembly includes a float arm connected to the wiper housing and a float connected to the float arm such that the float moves the float arm and the wiper housing relative to the variable resistor as a level of fuel increases and decreases in the fuel tank. The grounded wiper assembly further includes a conductor interconnecting the float arm and the wiper to bleed off electrical charges attached to fuel to ground.
