Beretta V6-173 2.8L (1989)
Fig. 14 Permanent Magnet Depressed Park Type Wiper Motor w/Remote Washer Pump
Wiper motor assembly consists of a permanent magnet wiper motor with either an integral flex-vane washer pump mounted in the cover, or with a
washer pump remotely mounted in the washer tank, Figs. 11 through 14. Depending upon the type control switch used and whether an optional control
board is included in the motor cover, the system can serve as either a standard or pulse type wiper. The timing functions along with the program and
demand wash functions are controlled by a printed circuit board permanently attached to the wiper cover.
Standard (Non-Pulse) Wiper Operation
Moving the multi-function lever to low or high speed position completes the respective brush circuit to 12 volt terminal at the multi-function lever and
motor runs at that speed.
An instantaneous wipe can be obtained by moving the multi-function lever to mist position. A continuous wipe will be performed if the button is held.
Pulse Wiper Operation
The multi-function lever in the DELAY mode can be turned from a minimum to a maximum position. Turning the control knob from minimum to
maximum position varies the amount of time wiper will delay between each wipe. Delay ranges between 0-12 seconds depending on knob position.
Minimum delay or 0 seconds between wipes provides equivalent of low speed continuous operation.
Moving the multi-function lever to low or high speed position completes the respective brush circuit to 12 volt terminal at the multi-function lever and
motor runs at that speed.
Moving the multi-function lever to pulse mode operates the motor intermittently and delay can be varied by moving switch back and forth in the delay
mode.
