The armature acts as a switch and completes the circuit that will have the high current flowing thru' it.When the electromagnet gets energized (by having current flow thru' it), it moves the armature to close against another set of contacts.Photo 2 of 3 (in the image viewer) shows the spring (bottom arrow).Photo 3 of 3 (in the image viewer) shows the armature (middle arrow) and two contacts.This is the part that completes the high current circuit by uniting the circuit that has voltage to the circuit that will deliver it to the component (fuel pump, cooling fan relay, etc.) that needs the voltage/current.Photo 2 of 3 (in the image viewer) shows the electromagnet (top arrow points to it).When energized with voltage, it becomes a magnet.This is a coil of wire wrapped around a soft iron core.The relay has the following core components inside.The relay we're talking about in this article is the mechanical type and works in the following way: The majority of relays accomplish this by mechanical means while others do it with a transistor. By activating I specifically mean allowing voltage to pass thru' the relay (internally) and on its way to the component that needs to activate (fuel pump, cooling fan relay, A/C compressor, etc.). The low current circuit is the control circuit that activates or deactivates the relay. This component could be a cooling fan motor, an A/C compressor, a fuel pump, you get the idea. The high current circuit is the one that delivers the voltage (and thus current) to the component that needs to activate. Well, every relay has two basic circuits and for the purpose of our discussion, we'll call them:īoth of these are completely independent from one another, in other words, voltage/current flowing thru' these circuits don't mix. The core purpose of a relay is to control a high amount of current with a smaller (lower) current. This section isn't mandatory reading to test the relay, but I know a lot of folks dig some working theory (I do myself when researching anything on the Internet) and so this section is for you. You'll need two of them with alligator clips on both ends (you can make these yourself).If you need to buy one or are looking to upgrade, check out my recommendations here: Buying A Digital Multimeter For Automotive Diagnostic Testing.A digital or analog multimeter will work.You need a few basic things and they are: This relay is used for the PCM, fuel pump, fan motors, and a bunch of other stuff. You can find this tutorial in Spanish here: Cómo Probar En Banco Un Relé De Ford (Relé Grande) (at: ). What Tools Do I Need To Test The Relay?.Will order a new window motor tomorrow so that problem will be solved. It did work but was moving very slowly, conncted the wires from the engine to the wiring loom in the door, it was just as slow as with an external battery.

took it off the car and connected it to a battery. The drivers side engine was full of old crap.thats way that one did not work. will double check the wiring tomorrow to test if i have switched the + and - wires going to one side of the button. Checked the switch after taking it appart and cleaning it.my friend did it the first time.and I discovered that he had put the brass plate on the back of the switch on the wrong way making a connection between - and - instead of + and +( meaning 12v only one side of the button making it go up and not down. I think at leas we now get the window engine to go up and down from the drivers side controlls, and up but not down on the passanger side controlls. We had the switch out and cleaned it.and wiring going in to the connector plastic socket fell out of the socket.we must have put it back in the wrong order, because when we followed the schematics. We did change the passanger side power window motor earlier.and it would not work after reinstalling it. Progress.I did find wiring schematics for the power window of 70 thunderbird.More or less the same.except from wiring colors.
