2. Working principle
The electronic flasher controls the on-off of the high-power FET through an IC chip, and
outputs a certain frequency voltage to make the turn signal light up. If a turn signal is
disconnected, the flash frequency will be significantly increased. The flasher also has the
function of short-circuit self-protection, and beeps when it is protected.
3. Basic parameters
Working voltage: 9-15V, Working load: 1-50W
Flash frequency of missing light: (90±30)
times/min.
4. Pin function
The turn signal cannot be turned on;
The interference triggers the relay by mistake
and makes knocking sound;
The turn signal lamp cannot flash;
Short circuit protection is triggered by interference;
The relay fails and cannot make knocking sound;
5. Possible failures
The turn signal cannot be turned on;
Knocking sound caused by interference and false triggering relay; Turn signal cannot
flash;
Short circuit protection is triggered by interference;
The relay fails and cannot make knocking sound;
When one turn-signal lamp is disconnected, flash rate has no obvious change; The pin is
Output
