It's called a _circuit_ because electrons have to flow around it. Both ways. There is no such thing as a ground, that's merely a simplification that is very useful sometimes. One of those times is _not_ a bidirectional DC motor circuit! If you didn't use two wires, you didn't do anything.
Another place to test your motor/regulator from is the correct two pins of the socket that takes the rear window switch. Should be 100% the same as testing from the terminal block inside the door. Don't connect a battery to the WRONG two terminals, though. That'll prove out the door hinge wiring. -- Jim _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
