Why does the motorcycle turn signal sometimes work and sometimes not?

[EmiliaMarie]

The reasons why the motorcycle turn signal sometimes works and sometimes not include a damaged relay, poor contact in the turn signal switch, or poor bulb contact. Inspection method for motorcycle instrument turn signal not working: Check if there is power for the fuel gauge, power indicator light, horn, etc. If there is no power, it may be a fault with the ignition switch, battery, or power supply. If there is power but all four turn signals are not working, the flasher may be damaged. You can directly inspect the flasher to see if there is power input. If the flasher-ignition switch still does not work, check the turn signal switch and the turn signal lights. Introduction to turn signals: Turn signals are important indicator lights that are turned on when a motor vehicle is turning to alert vehicles and pedestrians in front, behind, and on both sides. The turn signal tube uses a xenon tube, controlled by a single-chip microcomputer circuit, with alternating left and right flashing that works continuously. The turn signal uses a flasher to achieve light flashing. It can mainly be divided into three types: resistance wire type, capacitor type, and electronic type.
