Checking the relay-interrupter of direction indicators
1. Connect the battery to the terminals "2" (+) And "3" (-) relay.
2. Connect two turn signal lamps in parallel (21 W) to conclusions "1" And "3". Make sure the lamps are flashing at a rate of 60-120 times per minute.
3. If one of the turn signal bulbs burns out, the flashing frequency will be more than 140 times per minute.
4. If the operation of the turn signal breaker is not as described, replace it (first make sure that the power of the lamps corresponds to the rated).
