What is the reason for the constant illumination without flashing of the turn signal on the Besturn B70?

[SanAubrey]

Besturn B70 turn signal constantly illuminated without flashing may be caused by relay failure. The following is a detailed introduction to the issue of car turn signals staying on without flashing: 1. Causes of the fault: It may be caused by relay failure, and the fuse inside the relay can be replaced; It could also be due to a loose connection in the wiring, which requires inspection and can be done at a repair shop; The two wires of the flasher have polarity, and if they are connected in reverse, the light may stay on without flashing. Try swapping the two wires of the flasher. 2. Introduction: The turn signal is an important indicator light that is activated when a motor vehicle turns to alert vehicles and pedestrians in front, behind, and to the sides. The turn signal tube uses a xenon tube, controlled by a single-chip microcomputer circuit, with left and right alternating flashes working continuously. The turn signal uses a flasher to achieve light flashing, which can mainly be divided into three types: resistance wire type, capacitor type, and electronic type.
