Greetings . I think that the topic of modernizing the turn relay will be of some interest in the Community. During the first winter trips on the Niva VAZ2121/ perhaps due to sub-zero temperatures?/ the turn signal relay 231.37.47 failed. While driving, when the turn signal or hazard lights were turned on, they blinked rhythmically for 10-15 seconds and then “drizzle” chaotically with an unstable, jerky rhythm. Next, I outline the essence of the repair.

In stores now the most popular analogue for 231.37.47 (23.37.47) relyushka 71.3777-04
Kaluga plant "Energomash". It costs about 170-200 rubles.
Here is the purpose of the contacts: 1 - 12V, 2 - direction indicator lamps, 3 - control lamp, 4 - car body.
Before installing it directly on the car, I decided to test it at home on the table.
. I even simulated the fuse with a 0.05x5 wire (about 5 Amperes). Everything works fine. You turn off one lamp (it seems to have burned out) and it works at double the frequency. If you short circuit it, the fuse blows. But when the control lamp was closed in the circuit, it was discovered that it stopped working
