Where is the car reverse switch located?

Car reverse light switch location The reverse light switch is located in front of the gear shift mechanism directly above the transmission. The switch adjustment is as follows: The two wires connected to the light are not positive and negative, but are connected to the two contacts of the car reverse light switch. Engaging reverse gear is equivalent to short-circuiting these two wires, allowing power to be transmitted to the rear reverse light, which will then illuminate; Connect a test light to the two wires linked to the reverse light switch. These wires should be connected in series in the circuit, but the reverse light will only illuminate when the test light is on and the reverse light is off. If the two wires are short-circuited, the reverse light will turn on. This occurs because your test light has too low power. When connected in series, the test light receives a voltage drop, causing it to light up while the reverse light remains off. Lift the car. There is a plug located above the rear section of the transmission, which is the reverse switch. The working principle of the reverse light switch is that it is a normally open switch (normally closed). When the gear is in reverse, the mechanical mechanism presses the switch contacts to close the circuit, turning on the reverse light and activating the reverse warning sound. When reverse gear is disengaged, the switch contacts pop out, and the reverse light circuit is closed again. The reverse light switch in tractors is generally installed on the transmission and is triggered by a pit on the gear lever. During operation, due to the continuous high temperature of the transmission, the internal insulating rubber of the switch is prone to aging and failure, and the switch capacity is too small. Normally, when the two large lights at the rear of the tractor and the reverse buzzer are working simultaneously, the current passing through the switch can reach 7A, causing the contacts to easily produce sparks and burn out under high temperatures. The lifespan of the original reverse light switch is only about one month. Due to the limited installation space, replacement is inconvenient and time-consuming.
