I just recently aquired a 1973 450SE.

I have memorized the factory operations manual. Although very detailed about many things, including the wiper function, it does not say a word on how to active the windshield washers.

This model has an electric pump mounted on the right fender well under the tank. I hooked a meter on the pump leads, but could not get a response no matter what I pushed.

Anyone know for sure how to active the washers?

Thanks for the help..
