Pulse Operation

With the wiper switch in the DELAY (pulse) position, battery voltage is applied to the wiper motor connector at terminal B through circuit 143. Voltage is also applied to terminal 0 through circuit 113 and terminal E through circuit 112.

For variable-pulse systems, the length of delay time between sweeps is controlled by the variable-pulse delay resistor. Delay is adjustable from 1-22 seconds, nominally. For fixed-pulse systems, the length of delay time between sweeps is non-adjustable.
