The wiper delay described mounts under the dashboard, does not hinder normal wiper operation, and features a variable 2-18 second delay. The wiper delay schematic is shown. If an AC power supply is used, the transformer can be a small one since the circuit requires only 20 mA and practically any bridge rectifier can be used.
