General Description
The circuit is designed to drive the direction indicator flasher relay.
Figure 2 shows the typical system configuration with the external components.
Key Features
- overvoltage, defective lamp and short circuit detection. The lightbulbs L2, L3, L4, L5 are the turn signal indicators with the dashboard.
- light L6. When switch S1 is closed, after a time delay of t1 (in our example t1 = 75 ms), the relay will be actuated. The corresponding lightbulbs (L2, L3 or L4, L5) will flash at the oscillator frequency, independent of the battery voltage of 8.0 V to 18 V. The flashing cycle stops and the circuit is reset to the initial position when switch S1 is open.
