Holding Coil & Low Speed Switch Test

Without removing connectors at servo, place one test lamp lead to terminal with black wire (with tracer) and other lead to ground. Block front wheels, raise rear of vehicle, start vehicle and accelerate to 35 MPH. With slide switch in "ON" position, depress and release "SPEED SET" button. Speed should increase above 35 MPH and test lamp light should stay on. Depress brake pedal to disengage system and test lamp light should go out.
