How It Works The circuit diagram for the DATSM is shown in Fig. 8.1. When the directional-light switch is in the neutral position. capacitor C1 charges to battery voltage (12 volts) through resistor R4. When the turn signal is activated. the negative terminal of C1 is connected to battery voltage through D1 or D1. depending on whether the ... The Sonalert will continue to beep at the flasher rate as long as the directional signal switch is on. since the capacitor cannot recharge because itsanbsp;...
