Wipe Out

January 23rd, 2012 by Marine Ac/Dc

Kevin,

I have to replace a wiper motor which has only two wires and an “on and off” switch.

I’m going to replace with a AFI MRV #34000 which states I need a three-position switch. This would be very difficult to rewire though the windshield.

The vessel is a 1991 SeaRay 350. Is it possible to us the existing switch and boat wiring??

AFI wiper motor

Hi Gary,

If your current wiper has two wires, power and ground, connect the ground to the case on the MRV 34000 and the power to either speed 1 or speed 2 on wiper motor.

If your current wiper has three wires, power, park, and ground, connect the ground to the case, park (constant power from fuse or breaker) to the park wire on the wiper motor, and the switched power to either speed 1 or speed 2. Even though your new wiper motor has two speeds, you will only be able to control one.

Hope this helps,

Kevin
